The bestselling author of Close My Eyes returns with a chilling psychological thriller.

Julia has always been the friend that Livy turns to when life is difficult. United fifteen years ago by grief at the brutal murder of Livy's sister, Kara, they've always told each other everything.

Or so Livy thought.

So when Julia is found dead in her home, Livy cannot come to terms with the news that she chose to end her own life. The Julia that Livy knew was vibrant and vivacious, a far cry from the selfish neurotic that her family seem determined to paint her as.

Troubled by doubt but alone in her suspicions, Livy sets out to prove that Julia was in fact murdered. But little does she realise that digging into her best friend's private life will cause her to question everything she thought she knew about Julia. And the truth that Livy discovers will tear the very fabric of her own life apart.
