On the planet OtherWorld, Tara’s friend Cal is convicted of a crime he didn’t commit, and she and her friends set out to prove him innocent. It’s an unlikely crew: Tara, the riddle-loving Fabrice, Robin the half-elf, Sparrow the shape-shifting princess, and Tara’s cultured grandfather - and black Lab - Manitou. Blue gnomes help Cal break out of prison, but at a terrible price. To force him to help liberate their people from an evil wizard, they infect Cal with a time-release poison that Tara and her friends must race to neutralize. Helped by Fafnir the dwarf, they defeat the wizard and travel to Demonic Limbo for evidence of Cal’s innocence.
