Grades 4-6: Zac has been having nightmares recently, and it seems to be a worldwide epidemic. Zac finds out why when he follows his grandmother through a secret portal late one night: she reveals that she is a member of the Knights of Nod, a group of good magicians who are responsible for protecting the Wakelings (people from our world). This has been difficult lately, as a group of rogue magicians, the Dream Stealers, are determined to take control of the world through the magic generated by peoples' nightmares. It's up to Zac and some friends he makes along the way to help save humanity from the dark future of the Dream Stealers. This good versus evil battle doesn't have quite the character development or the plot twists of the Harry Potter series, but it's fun fantasy for kids who have decided they aren't going to read anything that doesn't have SOME resemblance to HP.

Though enjoyable, it was mostly unoriginal. The Leven Thumps series already has the whole "Dream World" concept covered, and the Percy Jackson & The Olympians, as well as the Heroes of Olympus and Kane Chronicles series, has the "prophetic dreams" concept.
