Sisters make the best flatmates ... except when they are both keeping terrible secrets.

The stunning new standalone psychological thriller from the author of the popular Detective Kate Miles series.

The dream apartment. The start of a grand adventure. And two lives about to unravel.

Devika is living her best life, moving out of home in her final year of university. Close to the beach and away from her mother. Independent and self-sufficient, just like Kalyani. There's just one awful secret that Kal can never find out about.

Kalyani has it made. A new job. A unit she can afford, and her little sister as her roomie. She's finally achieved the life she's always wanted. Except for the one big thing she's yet to confide in Devi. A truth that gets harder to reveal the longer she waits.

When their lives are torn apart by betrayal, and Kal refuses to forgive her sister, Devi must peel back everything she thought she knew to rediscover Kalyani, lie by lie and secret by secret.
