A Map for Wrecked Girls — Jessica Taylor

In this twisting tale of loyalty, betrayal, and love, two sisters must survive the wilds, if they can first survive each other -- for fans of Pretty Little Liars and Gone Girl.

Emma has always orbited Henri, her fierce, magnetic queen bee of an older sister, and the two have always been best friends. Until something happens that wrecks them.

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

Then the unthinkable occurs -- 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 in a gorgeous hell, Emma and Alex fall together as Emma and Henri fall catastrophically apart. To find their way home, the sisters must find their way back to each other. But there's no map for this. Can they survive the unearthing of the past and the upheaval of the present?

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