"All of the characters are believable, the dialogue is spot on, including the clever use of Aboriginal language in one of the characters, definitely a book written with a visual experience and would certainly be ideal to be portrayed as a movie. This reader certainly can’t wait for Book Three."

Review by Mary Anne Yarde for the Coffee Pot Book Club. Goodreads: 5 Stars

“As the sea spray lashed his face, Jamie reflected that his first Christmas in Darwin had become much more eventful than he had bargained for…”

They were in the middle of Christmas lunch when the distress call from a small boat off the north coast of Darwin was intercepted. Jamie Munro and Jack “Jacko” O’Brien from the Commonwealth Investigation Service (CIS) volunteered their services to help with the rescue. However, when they reached the boat, they saw a body of a young child floating in the water. One thing was for sure, this was no ordinary fishing boat, and these so-called fishermen were not whom they said they were. The discovery of a boy hiding under lifebelts and boat fenders in the bow of the boat only strengthen their suspicions.

Only one child survived the crossing, and it is from him that the two CIS officers had their fears confirmed. The boat had been smuggling children with the intention of selling them to wealthy paedophiles.

In their desperate bid to bring down the despicable men who were exploiting these children, Jamie and Jacko must travel to South East Asia, for that is where the children came from. However, they are faced with impossible odds, as those who have invested heavily in this smuggling operation will do absolutely anything to make sure it continues

Unbeknownst to Jamie and Jacko, the perpetrators of this disgusting crime are a great deal closer to home than either of them realised.

From the desperate plight of a young boy hiding on a boat to the vastness of the Australian outback, The Warramunga’s Aftermath of War by Greg Kater is the shocking yet gripping account of two CIS officers as they attempt to shut down a terrible paedophile ring. 

Initially, I was a little cautious about the topic of this book — I would usually avoid anything that has a plot about child exploitation. However, I was confident, after reading the first book in this series, that Kater would approach this subject with great sensitivity and care, which I am pleased to say he did. The story concentrates on Jamie and Jacko’s attempts to stop child smuggling rather than the suffering of the children themselves.

Kater wisely chose to add many lighter moments to this story, which worked very well and helped to give the book balance. However, saying that, at times the tension is almost unbearable, especially as Jamie and Jacko close in on their intended targets. It is undoubtedly a page-turning read and one I did not want to put down.

I must applaud Kater for his meticulous research. His depiction of the Philippines post-war was terrific. Kater has captured the essences of this era, and like a master bard, he has presented his readers with a believable backdrop in which to place his two wonderfully dynamic and incredibly appealing protagonists. When the story moves back to Australia, Kater once again demonstrates how good a writer he really is. To be in charge of such a large canvas, and to keep true to the historical facts of this era is no small thing. His portrait of the Blue Lagoon was a masterful triumph. But not only that, his portrayal of those who lived in this region was fabulous. Kater certainly knows how to bring his characters and the historical landscape to life.

I adored the characterisation of Jamie. He is such a brave and honourable man. A true hero. However, he is a bit of a contradiction — when faced with armed criminals he is calm, collected and confident, yet, when it comes to women, Jamie becomes a stuttering nervous wreck which makes him so very endearing. Jamie’s relationship with Carna is very sweet and tender and was one I enjoyed watching develop over the course of the story. Likewise, Jacko, and his wonderful half-sister, Sarah, continued to fascinate.

There is no doubt in my mind that The Warramunga’s Aftermath of War is a monumental work of scholarship. If you are looking for your next historical thriller, then this is the book for you.

I Highly Recommend.

Review by The Bookish Elf

Right off the bat, we meet our two main heroes, Jamie Munro and Jack O’Brien (also called Jacko). After their involvement in intelligence and counter-espionage during the war, they are now once again working together. This time as heads of the Darwin office of the Commonwealth Investigation Services (CIS). It’s an organization dealing both with garden-variety and uncommon criminals in the northern part of Australia.

After learning about a distress signal given by a fishing boat nearby, Jamie and Jacko set off to investigate. Much to their surprise, the boat is anything but a genuine fishing boat, and its cargo is strange one too. They found bodies of children floating around the boat and a living child hiding on the lower deck. They both suspect that the crew is involved in human trafficking. Soon they learn that, indeed, the criminals are involved in child trafficking for the pleasure of rich pedophiles. Thus begins their major investigation into the trafficking ring, where both are hell-bent on bringing the pervert criminals to justice.

The central theme of the first part of the book is a straightforward criminal investigation. In the second part, when the initial investigation came to an end, will surprise you. In many stories that would be the end of the story but not in The Warramunga’s Aftermath of War. It continued with a gripping adventure story set in the Australian wilderness involving tracking and taunting the enemy.

The story was solid, and the characters were well fleshed-out. Jacko is a half Warramunga aboriginal, who possesses some interesting tracking and survival skills; which helped him greatly during the cat and mouse spiel with the bad guys. While Jamie is an interesting character as well. He and his half-sister, Sarah, literally stole the show once they got their time in the limelight.

This book reveals the devastation that takes place in the Philippines as a result of the war. The author did a good job of describing some of the places in utter ruins. This explains why there were children who are left orphaned, and easy for the smugglers to take advantage of. This would interest those who study history and the results of warfare.

The criminals in book were hard to pick out because author would initially introduce characters to be appeared on “up-and-up”. He reveals their true intentions at a later time. Also, there were a lot of characters to keep track of, which might be confusing to some. Those who like mysteries could get caught up in the chase to capture the guilty parties.

The relationships and the culture add another dimension to the novel. The religious or class differences of the romantic couples do not deter them in any way.

Review by Kirkus Reviews

A sequel chronicles the continuing adventures of two Australian intelligence officers in the postwar Pacific. 

After their counterespionage duties in North Africa and subsequent work back in Australia to bring a murderous gang to justice, white officer Jamie Munro and his partner, the excellent tracker of half-Aboriginal descent Jacko O’Brien, are hoping that the remainder of their time with the Commonwealth Investigation Service will be a little quieter. Not so. When reports of a stranded ship reach them during Christmas lunch at the Hotel Darwin, the duo goes out to lend a hand. Approaching the storm-tossed ship, Jamie spots something in the waves: “As they came alongside the object, it appeared to be a small human body. They hauled the body into the cutter using a gaff and saw that it was indeed the body of a small boy.” Even more disturbingly, another child is found in the hull of the ship, this one alive but very scared. It seems that the vessel is trafficking children, though for what purpose Jamie and Jacko must investigate. The case brings them to the Philippines, where the destruction wrought by World War II has left thousands of orphans easy prey for predators and kidnappers. In their quest to find out who is buying these children, the CIS officers will probe deeper than perhaps is wise—especially when it provokes the kidnappers into taking one of their own. In this second installment of a trilogy, Kater’s (The Warramunga’s War, 2018) prose is reliably sharp and gripping, particularly when describing the devastation of the war: “They drew closer to the port area, where most of the buildings had been reduced to rubble and were covered in weeds, while those still standing were empty and badly damaged. The ground was heavily potholed and most trees seemed to have been cut to shreds.” This work feels more confident than the author’s previous Warramunga effort, and hews more closely to a traditional plot structure. The milieu is captivating and the characters are likable, which, when coupled with a perfectly serviceable crime story involving a shadowy syndicate, make for a pleasing bit of escapism.

A colorful and engrossing thriller set in Australia and the Philippines.

This organization is responsible for intelligence and counter-espionage as well as investigating the criminal activities in northern Australia and the surrounding areas. Jamie and Jacko are caught up in an investigation into a criminal organization with reaches into Australia, the USA, and SE Asia. An investigation into a fishing boat in distress in the seas of northeast Darwin leads the intrepid detectives to a shadowy organization run by powerful pedophiles involved with human trafficking.

The story is filled with powerful and deeply emotional moments with danger strewn in at unexpected moments. The plot is enriched by the author’s fine sense of setting, capturing elements of the culture and life in the Philippines and the post-war social climate in great detail. Greg Kater carefully weaves backstory into the narrative, yet ensures it doesn’t come across as a distraction to readers. The characters are realistic and it is interesting how well the background of the half Warramunga character, Jacko, is developed. The Warramunga's Aftermath of War is an interesting read, filled with relevant social and political commentaries, a narrative with well drawn and sophisticated characters, and themes that are both timely and strong. It will have a strong appeal to fans of historical novels with post-war settings.

  • Greg Kater's second book in the Warramunga series does not disappoint. For those seeking a realistic 1940s Action- Adventure novel, this is it. The story reads like a period movie filled with thrills and characters the reader will want to know. Jamie and Jacko are home from the war and working for the Australian Commonwealth Investigative Service. The war's end, however, does not mean peace and quiet for those who have survived. There are still war crimes to prosecute, and as Jamie and Jacko discover there, others are willing to take advantage of the chaos that war has brought. Jamie, Jacko and their new allies discover an international child kidnapping/pedophile ring and seek to put a stop to it. Offsetting this appalling crime, Kater manages to capture the setting of and culture of the Philippines in an exceptional way. Very well written to the point that one would think Kater was a first-hand witness to the events. Characters and settings are extremely well done

Review by Ella James of ARTISAN BOOK REVIEWS

The Warramunga’s Aftermath of War by Greg Kater follows former Army Officer Jamie Munro and his friend and colleague and Warramunga Aborigine Jacko O’Brien as they follow yet another assignment in their investigative roles within the Commonwealth Investigation Service in Darwin, Australia. Set just after the war in late 1945, Jamie and Jacko find themselves in the Philippines tracking down a child smuggling ring, which comes to light after a smuggler’s boat runs into difficulties during a storm. One young survivor is able to tell the awful story of child abduction on the streets of the Philippines, and Jamie and Jacko find themselves tackling sordid crimes, murderous perpetrators, and lawless cutthroats, all fearless and motivated by greed. Interwoven in this sinister plot are sub-plots of kidnapping, blackmail, and extortion which leaves the reader breathless with anticipation and rooting for Jamie and Jacko as they put their very lives at risk in the name of justice.

The author, Greg Kater, writes with incredible description which transports the reader into the Australian bush world, where there are no rules of right or wrong, no-one can be trusted, and hungry crocodiles hunt for unsuspecting human prey. For lovers of pine-tingling adventure, this book is for you. The pace races and never drops, leaving the reader turning pages frantically to find out what happens next in such an exciting experience – because that is what this book is, a reading experience. Somehow, the author has managed to combine all this excitement with a little piece of humour and a touch of romance, making it a well-rounded, well-developed novel that is spell-binding in its authenticity.

The Warramunga’s Aftermath of War is the second book in a trilogy. Book one introduces the reader to Jamie and Jacko, and this second book follows them on an adventure in the Australian Outback that is truly captivating. All of the characters are believable, the dialogue is spot on, including the clever use of Aboriginal language in one of the characters, definitely a book written with a visual experience and would certainly be ideal to be portrayed as a movie. This reader certainly can’t wait for Book Three.
