Vanishing acts - Jodi Picoult

Why would a man who loved his wife - so much that in the quarter century since her death, he hasn't found someone to take her place - why wouldn't he have a record of the life he'd had with her, of the baby they'd made?

Delia Hopkins has led a charmed life. Raised in rural New Hampshire by her widowed father Andrew, she now has a young daughter, a handsome fiancé, and a job she loves, finding missing persons.

But as Delia plans her wedding, she is plagued by flashbacks of a life she can't recall. And then a policeman knocks at her door, and her world fractures into something unrecognisable...
