'Unpredictable, challenging and compelling' Sophie Hannah

From the first time I saw them together I knew it felt wrong. I didn't like the way he touched her or the self-conscious way he played with Molly and Luke. Joanne saw none of it of course. So I did it to prove to her that she was wrong. I did it for us.

Emily's instincts tell her that best friend Joanne's new boyfriend is bad news. Emily fears for Joanne. Fears for Joanne's children. But Joanne won't listen because she's in love. So Emily watches, and waits . . . and then she makes a choice.

But Emily has a past, and secrets too. And is she really as good a friend to Joanne as she claims?
