The Dark Room: Minette Walters

When Jane 'Jinx' Kingsley, daughter of a ruthless millionaire, emerges from a coma, she remembers nothing of the last few days: not that she's been jilted by her fiance Leo and betrayed by Meg, her best friend, nor her own supposed suicide attempt. With the disappearance of Leo and Meg, Jinx is haunted by terrifying flashes of memory - and the police seem determined to trap her into an admission of murder. While they investigate, she faces the worst nightmare of her life - unravelling the truth.
