Nellie just wanted to live the life she’d always dreamed about with Richard. But who is his ex-wife, Vanessa?

Nellie thinks she knows everything about his previous marriage. That it was a disaster, plain and simple. But, as secrets are unearthed, she starts to think that maybe there is more to the wife before her . . .

Only one thing is certain. She is not who you think she is.
