LONG BRIGHT RIVER meets "Lost" in this adrenaline-fueled thriller of a missing plane, a remote island, and two sisters torn apart when a vacation turns unthinkably deadly.

Two years ago, a small plane disappeared over Fiji. For Erin, it’s been two years of obsessing over every detail, refusing to move forward even as life does. Her sister, Lori, was on that plane, and Erin was meant to be, too. But after a bitter argument, she failed to show. Everyone thinks Lori is dead, but Erin can’t let go.

Just when Erin is on the verge of losing hope, the pilot of the missing plane turns up still in Fiji, seemingly with no memory of the crash. In a final bid to find her sister, Erin travels there herself. But what she discovers is beyond anything she could have predicted.

A sharp-edged, darkly propulsive novel following two sisters whose lives are upended when their vacation of a lifetime goes disastrously awry, THE CASTAWAYS is another scorcher from “queen of the destination thriller” (Claire Douglas) and million-copy bestselling author Lucy Clarke.
