Hannah has always been wary of commitment, but when she meets Mark, a fellow Brit, one hot New York summer, her ideas change. Within months, they are married, and she has moved back to London to be with him, leaving her life in New York behind.
But when Mark fails to return from a business trip, her certainty about their marriage starts to crack. Why don't his colleagues know about the trip? Who is the woman who keeps calling his office? And why has Hannah's bank account been emptied?
Hannah's questions will uncover secrets that throw into doubt everything she has believed about her husband, secrets that lead her to a place of violence and fear.
Can you ever really know what happened before you met?
