A gate has been opened. The Old Ones have been released. And now the third and fourth of The Five -- twins with a mysterious psychic bond -- are joining the fight....

Hailed "a master of edge-of-your-seat writing" by Booklist, Anthony Horowitz pens the New York Times best-selling Gatekeepers series, which includes the action-packed novels Raven's Gate and Evil Star.

With Nightrise, he amplifies the suspense as an evil group strives to imprison and control the psychic twins, Scott and Jamie.
