The president of the United States is shot in the head by a would-be assassin. Rushed to hospital and barely saved from death, he discovers that he has new memories - memories that are not his own.
A scientific experiment has gone awry, and a small group of people now remember each other's lives. And when one of those people's lives involved access to the most secret and dangerous information in the world, everything will change.
Canadian futurist Sawyer (Flashforward) builds a turbo-charged techno-thriller around an experimental memory-altering machine. After an assassination attempt, U.S. President Jerrison is rushed into surgery. Minutes later, a bomb explodes at the White House. Dr. Ranjip Singh is working with a veteran recovering from flashbacks when an energy surge from the explosion overloads his equipment and puts his patient's into Jerrison's mind. The event also swaps around the memories of the surgeon, Dr. Singh, Secret Service agent Susan Dawson, and several others including someone who now has access to Jerrison's memories on the eve of a major secret military operation. Interleaving the stories of 21 people suddenly involved more intimately than spouses, Sawyer offers an escape from the recent run of near-future dystopias in a combination of classic and contemporary science fiction.
