Resourceful kids battle hordes of the walking dead.Residents of several Northern California counties are being advised to evacuate and "flee to safety" in the wake of a zombie epidemic. Lucy Santifer and her family just make it to their car when they are attacked and killed. Nearby, Lucy's best friend, 12-year-old Joule Artis, climbs into her treehouse, the better to seek her missing father. Elsewhere, 11-year-old Oliver Wachs is holed up in the Redwood Zombie Brigade Headquarters, stocked with weaponry and populated by dedicated zombiefighters. And Regina, 12, is haunted by her narrow zombie escapes even as her mother, Dr. Celeste Herrera, unveils Project Coloma, an ingenious system that uses a zombie treadmill situated in an abandoned gold mine to create much-needed energy for the region. Weinberger's monster thriller is long on suspense, with several close calls but no graphic violence. The action pings briskly among the three young protagonists, and the punchy prose is suitably pitched to a preteen readership. The plot thickens with the forecast of a Rogue Wave of zombies headed to town. The trio eventually joins forces, promising further fights for freedom. If this horror thrill ride makes readers want to join the zombiefighters, note that there is a video game tie-in. Play at your own risk. Oliver reads white, Regina is cued Latina, and Joule is minimally described and racially ambiguous.Nonstop, action-packed, episodic exploits against the voracious undead.
