Spring is in the air, and a radical group of "Repopulationists"--Better known as Rabbits--are restless and ready to multiply. Unfortunately, these zealots manage to destroy a crucial barrier in north Seattle, unleashing the undead into the city. It's not good news for Sadie Walker, who's trying to live a normal life and raise her nephew in peace--when he's kidnapped by Rabbits. Now she's got to fight off zombies and zanies and sail a shipload of survivors to safety when she'd love to tell them all to get a life. But hey, it is the zombie apocalypse, after all.
