Tory and her friends have mutated animal DNA which gives them special powers and a “pack” mentality. They will need all these powers to survive the “Game,” a challenge they found in a geocache. It is only as they solve first one challenge and then the next that they realize that the “Gamemaster” is not a fellow geocacher, and the game is anything but a game. The Gamemaster has planted a bomb that will go off if the four friends cannot solve the clues.

I have not read the first two books in the series, but I was able to follow  the storyline although I think I would have enjoyed it more if I had had more background. The pack is a lot like Maximum Ride’s flock, but there is more suspense than science fiction in the story. The plot moves quickly in spots, less quickly in others. There is one ongoing subplot that is impossible to make sense of without having read the first two books, but I still enjoyed this one. Fans of Maximum Ride and Alex Rider should enjoy this series.
