Hatchet meets Raina Telgemeier’s Sisters in this adventurous and heartfelt middle grade tale of three warring sisters who find themselves lost in the wilderness and must learn to trust each other if they want to survive.

Sisters Abby, Emma, and Ollie have gone from being best friends forever to mortal enemies.

Thanks to their months-long feud, they are sent to Camp Unplugged, a girls’ camp deep in the heart of the Idaho mountains where they will go “back to nature”—which means no cell phones, no internet, and no communicating with the outside world. For two whole weeks. During that time, they had better learn to get along again, their parents tell them. Or else.

The sisters don’t see any way they can ever forgive each other for what they’ve done, no matter how many hikes and campfire songs they’re forced to participate in. But then disaster strikes, and they find themselves lost and alone in the wilderness. They will have to outrun a raging wildfire, make it through a turbulent river, escape bears and mountain lions and ticks. They don’t have training, or food, or enough supplies. All they have is each other.

And maybe, just maybe, it will be enough to survive.
