From the New York Times bestselling author of Five Total Strangers comes a thriller about a group of four classmates forced to navigate the wilderness for a school project with nothing but the pages of a survival handbook-and each other-before the sun goes down..

When classmates Baxter, Abigail, Turner and Emerson are forced to go to the middle of nowhere for a school project, they think things can't get much worse. Why on earth do they need to learn how to survive in the wilderness by an eccentric instructor?

But what starts off as a weekend of team building turns dangerous when their instructor goes missing and they are left with nothing but the pages of a survival handbook to complete a series of challenges.

They will soon discover the woods around them have unexpected surprises that might go beyond the obstacles their teacher set out for them...but will they find they can work together to find their teacher?

A recommended choice for classroom discussions and educators looking for survival books for kids.
