"What's your favourite song?" If you answered, "Nothing, sir! Music is evil!" then you probably live in the land of Bravura, where the wicked Czar has outlawed music and all artists have been imprisoned or exiled.

As if that wasn't bad enough, the Alephs, magical creatures that eat music with their ears, are slowly becoming extinct. Fortunately, Zeb and his best friend Flip are armed with magic, courage and weaponised toffee and they are about to begin their quest to bring back the legendary musician Smokey Waters so that he can restore the land with his Ruckus Music. Along the way they'll face the Czar's admonishers, steelhawks, bewilderbeasts and the most fearsome creature of all, the cave-dwelling Ruttersnarl. At least they'll have an excuse for not finishing their homework...
