Róisín Burns has spent the last 20 years becoming someone else. The secrets she has kept since she was a naive schoolgirl in Belfast have blighted her existence and ruined her relationships; her life in New York is built on lies. Things are beginning to fall apart when a figure from her past flashes up on the news: it’s the man who stole her life. These days Brian Lonergan is a smooth, sharp-suited politician, a family man, the darling of the Irish press. But scandal is brewing and Róisín knows the truth. Armed with the evidence that could ruin him, she travels back across the Atlantic to the remote Lamb Island to hunt him down. But Lonergan is one step ahead, and when she arrives on the island, someone else is waiting for her.
