''Haunting. Mesmerising. Unforgettable.'' Gillian Flynn, author of Gone Girl

Don''t be left in the dark.

In the hushed aftermath of a total eclipse, Laura witnesses a brutal attack. She and her boyfriend Kit call the police, and in that moment, four lives change forever.

Fifteen years on, Laura and Kit live in fear.

And while Laura knows she was right to speak out, she also knows that you can never see the whole picture: something is always hidden . . . something she never could have guessed.
