For fans of We Were Liars and from the bestselling author of Dark and Shallow Lies comes a paranormal thriller about a seventeen-year-old girl returning to camp to uncover the truth of what really happened there twelve years ago, the night her mother drowned.

Twelve years ago, Avril's mother drowned at Whisper Cove theater, just off the rocky Connecticut coastline. It was ruled an accident, but Avril's never been totally convinced. Local legend claims that the women in the waves-ghosts from old whaling stories-called her mother into the ocean with their whispering. Because, as they say at Whisper Cove, what the sea wants, the sea will have.

While Avril doesn't believe in ghosts, she knows there are lots of different ways for places, and people, to be haunted. She's spent the past twelve years trying to make sense of the strange bits and pieces she does remember from the night she lost her mother. Stars falling into the sea. A blinding light. A tight grip on her wrist. The odd sensation of flying. Now, at seventeen, she's returning to Whisper Cove for the first time, and she might finally unravel the mystery of what really happened.

As Avril becomes more involved with camp director Willa and her mysterious son Cole, Whisper Cove reveals itself to her. Distances seem to shift in the strange fog. Echoes of long-past moments bounce off the marsh. And Avril keeps meeting herself-and her dead mother-late at night, at the edge of the ocean.

The truth Avril seeks is ready to be discovered. But it will come at a terrible cost.
