"This uneasy, compelling novel begins with a nighttime accident on the streets of Paris. The unnamed narrator, a teenage boy, is hit by a car whose driver he vaguely recalls having met before. The mysterious ensuing events, involving a police van, a dose of ether, awakening in a strange hospital, and the disappearance of the woman driver, culminate in a packet being pressed into the boy's hand. It is an envelope stuffed full of bank notes. The confusion only deepens as the characters grow increasingly apprehensive; meanwhile, readers are held spellbound." -- Provided by publisher

Dr. Jonas Cullen has spent his career as a groundbreaking physicist defying the odds.

Gutted by pain, Jonas sets out to find a way to bring back Amanda--or rather, find a parallel universe in which she's still alive. But that's easier said than done. As Jonas comes to understand all too well, the universe favors certain outcomes...and Amanda's death is one of them. Guggenheim's novel takes readers on a suspenseful journey, intercutting scenes of Jonas's frantic, present-day search across multiple realities with glimpses from the past of his unfolding romance and eventual marriage. Will Jonas and Amanda reunite in some other world, or will fate succeed in taking her from him forever?" --
