It was a very good book in general and it finishes the series off. The series was very good because it was a well thought out story line. It’s an action crime genre . In the book two of Zacks best friends are kidnapped and in the book zak Malcolm and Ricky try to find them. Malcolm dies on the way there however they’re all end up fine and the friends are rescued.

I, personally believe that this book is one of the greatest works of Chris Ryan (having read many of his fiction works, along with series like Code Red etc...) alongside Codebreaker (Agent 21 #3). I was starting to get a bit disappointed with Under Cover, but this just made me feel great. Great job!



Overall: Really loved the book, and I'm going to keep buying copies of the Agent 21 series till it is over, hopefully. Great Read for whatever mood!

PS:- Not really used to reviews, more to rating, so please forgive me if there is anything I have done wrong. Thanks!

Beautifully written yet severely heart-wrenching.





Overall, yet another amazing work from Chris Ryan. The amount of realism in the portrayal of Zak and company's journey for the 'Endgame' was action-packed and had me on edge the entire time I was reading. It was also heavily emphasized how much lives are so valuable and so quick to be lost.

I do hope another installment of this series comes around, with hopefully, something good coming into Zak's life. Please.

A Good book that fits in well with the rest of the series. I enjoyed reading about both Zak and Ricky but the plot was a little repetitive, I thought previous books in the series were more engaging. Overall an excellent book to kill time and great for fans of action. I will definitely be buying more books in the series if/when they come out.

I loved this book! It was brilliant! This set keeps getting better and better! I do love Chris Ryan's YA books they are always so well done and so much fun! It was a nice, quick and easy read that was really enjoyable. The storyline as always was good and well thought out. It tied up a story that had been ongoing throughout the series. 5 stars loads of fun!

Another book in the Zak Darke series. Is a thriller binge-reader I felt like this book fitted the criteria of a thriller. It was a good book, however it was not really a “good ending” in the sense that due to this being the last book there usually is a grand ending or a cliffhanger leading to a new series. In this book there was nothing of that sort. Apart from the usual cast we actually got to see the 2 kid agents work together, I would have honestly preferred it if they worked together in most of the books. The killing of Malcom was quite an unexpected twist while the killing of Cruz I expected to be a bit more dramatic. I’m kind of bummed out that series ended as it was a great series to read, I would recommend this book to thriller readers.

Definitely weaker, this one; clearly intended to wrap up the series, and maybe a little writer-fatigue shows through. It did not sadden me that there would be no more Agent 21 stories… Overall, the first book I read in this series takes the prize: No. 5, "Under Cover" clearly outstrips the rest, to my mind. It has a different protagonist and a different supporting cast, and somehow has a lot more zip and snap.

4 Stars!

This read was a long time coming. I’ve been reading the series since it began, and have put off finishing it for so long.

It had all of the action of the other books, but I couldn’t help that it felt a little lacklustre in parts. The book started off solidly with some surprises and the formation of a plan, but of course, plans tend to go awry. From there, it seemed more like a survivalist book than I spy novel, and although I loved reading about Zak and Ricky working as a team, it still fell a little short.

I also thought that Cruz would be more present in the story, and so, as Zak’s arch-nemesis, I couldn’t help but be disappointed that he didn’t play a bigger role in the final book.

Having said that, I liked that the book mainly shifted between Zak and Ricky’s POV, mainly because it gave cause to see just how far Zak had come since book one. It’s amazing and kind of scary, I’m not going to lie.

Overall: A solid if underwhelming finale to a action-packed spy series.
