This series is got better with every book! This is the firth and final book in the Liars series. (At least that we know of to date. But more on that later.) I am very thankful that the eBooks are available globally. It would have been terribly disappointing to have read the first book and then not been able to get the rest. That has happened to me with a couple of other authors from down under. This book and whole series are great MG/YA reads. It has a very fast pace. Lots of action and Jarli and his friends getting caught in the culmination of master criminal Viper’s plots.

This story begins with viper releasing a video stating that they are going to release a biological weapon on the town of Kelton. The town is in the process of evacuating when Jarli realized that things are even worse off than he expected. He bolts from a car and heads back to Kelton. Connecting up with his friend Anya and her father they head back into town to break back into prison to free some abandoned friends and family. But as we have come to learn, when it comes to Viper nothing is as simple as you plan or hope. And soon the team is separated, has been divided. And Jarli finally figures out who Viper really is and why they are doing what they are doing.

The whole series has action galore. But this installment has even more. It practically races from the beginning to the final confrontation. The characters are great, and I will be honest and state the main twist took me completely by surprise. One of the strengths of the series are the characters, Jarli, Anya, Doug, and Bess. Jarli and Bess were already great friends but the four of them grew closer together through the adventures and trials they faced.

This was a series I loved. It is written for a late Middle Grade or early young adult audience. But it is simply a great series that can be enjoyed by readers of any age. This book and the entire series are very well written. I think the books would make an excellent miniseries on TV. I am sure if you give this series a try you will be entertained! Heath has written a great story, and I honestly hope we encounter the characters again, in either a continuation or another series with them at the center of events. This is a great book and series!

SqueeeBoooom. Wow. Jack Heath has managed to pull it off. The biggest action packed series for kids, ever.
This is the fifth and final instalment of Jarli and his Truth App. The truth - it’s something that complicates life more than anyone could possibly imagine.

Jarli and his talented friends have their lives on the line once again....saving Kelton - the small town where they live......saving each other.....working out who they can trust....working out who Viper is and how can they stop him.

I hope the talented Mr Heath has more up his voluminous sleeve......once my library crew have devoured this, they’ll be begging for more.

A brilliant series with plenty of twists and turns to excite and delight young and old(er) readers. A satisfying end to the five books that sees good triumphing over evil even when life gets complicated. Great for reluctant readers. Please someone make this into a movie!!!!

READ FOR WORK

Satisfying conclusion to the series? Maybe. Vipers reveal was a little anticlimactic but in the same breath it also made sense. Their characterisation was always a little wishy-washy so I can’t be too mad, I just wish there was more clues and set up throughout the other books, maybe a red herring or two thrown in, a little more explanation… but then again these books are for people almost two decades younger than me so..

Wow.

Awesome. Best one of the series, with so many plot twists! Seriously though, that part about Viper adding memories, that was creepy! As she told Jarli, zillions of different scenarios ran through my head on what would happen next! But reading the next paragraph, relief washed through me ;)
Would definitely recommend though :D

Viper's identity is finally revealed in this book. When I first read it, I didn't like it very much for some reason but now, on this re-read, I think it is the best in the series.
