Ravenspell: The Wizard of Ooze

When the evil wormlord Sebaceous Ooze uses his magical song to enslave mice to dig a volcano that will help him and his slobber goblin armies take over the world, it's up to Amber, a mouse with magical powers, to stop him. With her devoted friends by her side — Ben, a mouse who used to be a human boy; Thorn, a genius mouse; and Bushmaster, the wise vole — Amber might stand a chance of thwarting the giant worm's sinister plan. But with a human army on their tails and betrayal in their path, these rodents are on a quest far more dangerous than any of them anticipated. This thrilling and exciting sequel to Of Mice and Magic will be loved by both the young and young at heart.
