A trapped cosmic creature may drive the whole world mad--unless the spellsinger can set it free: "Foster knows how to spin a yarn" (Starlog). It's an ordinary day in the Bellwoods, save for the fact that Jon-Tom the spellsinger has awoken as a six-foot blue crab. He soon reverts to normal--as normal as a college student trapped in a world of magic and talking animals can be, anyway--but the bizarre changes keep happening, affecting not just him but the whole of this strange world. His wizardly mentor suspects these are the effects of the perambulator, a cosmic being whose presence distorts reality. One has been imprisoned in the mountains, and unless they free it, it will rip the world to shreds one insane illusion at a time. So Jon-Tom sets out, backed by the wizard, a boozehound owl, a gutter-minded otter, and a warrior koala with a taste for leather. Saving the world will be a cinch, as long as they don't lose their minds along the way.
