The 4400 by Rene Echevarria and Scott Peters
One night the National Threat Assessment Command (NTAC) notice a comet coming straight for Earth, but things get strange when it appears to be coming in for a landing. A strange beam of light, and 4400 people are deposited on Highland Beach in Washington. Now NTAC is in charge of figuring out who these people are, and where they come from. Taken from their time, starting in 1946, all of these people haven’t aged a day, and many discover they have supernatural powers. But who brought them here? And how will they fit into the now?
