Fifteen-year-old Bobby Pendragon has visited the alternate dimension of Denduron (The Merchant of Death), explored the endangered underworld territory of Cloral (The Lost City of Faar), and traveled back in time on his own planet Earth to uncover the evil plot of the fiendish Saint Dane--the evil force behind all these interworld exploits (The Never War). Now he "flumes" (a kind of time/space travel) into the territory of Veelox expecting to wage another battle against evil... only to find all is peaceful. He quickly discovers the peace is due to the fact that most of the citizens of Veelox have become addicted to Lifelight, a virtual reality lifestyle. Unfortunately, what once seemed so safe and enjoyable has taken a frightening twist, and Bobby must rely on a Veelox Traveler named Aja to help him find a solution--and save the territory. His antagonistic relationship with the brilliant Aja grates on his nerves as she spits out cryptic words of wisdom: "Salvation here can be found in only one place: the imagination. If you can't understand that, you might as well flume out right now." Fans of D.J. MacHale's Pendragon series will enjoy this latest entry, and look forward to the forthcoming fifth title. The attraction of the series is not so much great writing or character development as fast-paced action and edge-of-seat danger. (Ages 9 to 12) --Emilie Coulter
