As fourteen-year-old telepathic twins struggle to escape the clutches of the Nightrise Corporation, one of them travels through dreams to a time when the evil Old Ones ruled and learns the role that he, his brother, and three other Gatekeepers must play to keep the world safe from the Old Ones' return.

Matt is being punished for a crime he saw, but didn't commit. Instead of being locked up, he is being sent to the middle of nowhere to live with a new foster mom, as part of a government scheme called The Leaf Project. But Matt's new home provides anything but peace and quiet. His new guardian is involved in very sinister things . . . and the whole town seems to be on her side.
