Four kids . . .
Two weeks in the Florida Everglades . . .
One top-secret science experiment that could change them and the world as they know it . . .
Meet football-star Quentin, hockey-player Sarah, horse-lover Ben, and artistic bird-watcher Cat. The four have little in common-except the head injuries that landed them in an elite brainscience center in the wild swamps of Florida. The clinic promises to return their lives to normal, but as days pass, the kids notice strange side effects and unexplained changes. Something about this clinic isn't right, and if they can't overcome their injuries—and their differences—to escape, they could lose themselves forever. . . .
