Jon-Tom just wanted to go home. Trapped in a world where animals speak and magic is real, the American college student yearned for an ordinary dorm-room life. But here his music has magical power — even if he can’t control it — which may be able to save the world from the army of the Plated Folk, whose sinister queen plans on killing and eating every warm-blooded mammal she can get her pincers on and taking over their lands.

Far to the south of the peaceful Bellwoods, where Jon-Tom the spellsinger continues trying to master the art of turning music into magic, a sinister force has awakened: a magician with great ambition and unheard-of power. He summons lightning to do his bidding, commands an army of faceless flying demons, and claims to come from another world — one Jon-Tom suspects might be his own. If he can somehow reason with the unknown magician, perhaps they can combine their talents and find a way to go home together.

Jonathan Thomas Meriweather is a typical college student, interested in girls, music, and an occasional taste of reefer. But when a journey through an interdimensional portal lands him in a world of talking animals and ominous sorcery, he finds he is on a very different trip indeed. Here, when he plays a strange instrument called a duar, peculiar things happen: powerful magic that may be the only way to stop a dark force that threatens his new world — and his old one. 

Jon-Tom has been trapped in a strange land of talking owls and wizarding turtles for a year now, his sole consolation that in this universe his musical abilities have inadvertently made him something of a sorcerer. But when an encounter with some burglars leads to him snapping the magical duar that channels his power, he finds himself an ordinary human again — on a quest to repair his instrument with nothing but his staff and his semi-faithful, ever-complaining otter sidekick to defend him.

Much to Clothahump the Wizard's distress, ex-hippie Jon-Tom and Talea's son Buncan wants to be a questing hero, but not a spellsinger. Instead he forms a band with Mudge's kids, otters Noctor and Squill, one that creates a wild unpredictable magic - based on rap! Then an anteater arrives with rumours about a dangerous legend. Soon the young rappers, aided by a drunk rhino, are off on an odyssey to a fortress where evil sorcerers threaten the world. And where only the unknown power of Buncan's beat can stop the hordes of hideous hybrids.
