"A masterfully written tale of survival, sisters, and love." --Julie Murphy, author of the #1 New York Times bestseller Dumplin'

In this twisting tale of loyalty, betrayal, and hope, two sisters must survive the wilds, if they can first survive each other--for fans of Tell Me Three Things, The One Memory of Flora Banks, and Pretty Little Liars.

Emma had always orbited Henri, her fierce, magnetic older sister, and the two had always been best friends. Until something happenned that wrecked them.

I'd trusted Henri more than I'd trusted myself. Wherever she told me to go, I'd follow.

Now the unthinkable occurrs--a watery nightmare off the dazzling coast. The girls wash up on shore, stranded. Their only companion is Alex, a troubled boy agonizing over his own secrets. Trapped on a gorgeous hell of an island, Emma and Alex fall together as Emma and Henri fall further apart. To find their way home, the sisters must find their way back to each other. But will Henri ever forgive Emma? Can they survive this island? Can they reclaim what they've lost? There is no map for this.

For the first time, I was afraid we'd die on this shore.
