Jake isn't sure why he agreed to take his twin brother's place on the flight to London. But when he wakes up in a hospital after the crash, he can't even remember his own name, or the woman, Caitlin, his wife, who watches him so intently. To Caitlin her husband seems like a stranger to her--a man who assumes there's love where none exists. He is totally different, like the man she thought she'd married. Until his memory returns--and with it danger.
