The Unstoppable series seems like an impossible mission at first but as Jude Watson reveals tidbits of information, mission impossible becomes mission crazy ( even for a lunatic).

I liked the book at first but as it went on, there were some unnecessary details. I mean, if you have read the previous books, you might find that this book isn’t quite up to the standard. The book though, has another one of the trademark 39 clue’s cliffhangers.

Dan figures out that the serum was not completely destroyed and blames himself while Nellie discovers that a hacker is trying to access secure Cahill files. The book ends with a mysterious observation by Amy and she sends Jake and Atticus home.

The book is a perfect combination of the previous series and I hope to see more coming.
