"For Queen, for Country, and for....Uncle Rabbit?" Just when Barnabas and Wilfred thought the world was safe at last, along comes a new threat: the Mayan Lords of Death have hatched a plan to overthrow the natural order of things, involving a cursed serpent god, two untrustworthy sets of twins, and a dead bunny that must be resuscitated at all costs. Only Barnabas and Wilfred can possibly unravel the convoluted plot, but they face danger after danger as they attempt to do so. If they fail, up will be down and down will be up, and the evil Lords of Death will take over the heavens. Do Barnabas and Wilfred have the courage, skill (and luck!) to save the world yet again?
