Tara Duncan and the Forbidden Book

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. There, Tara has a wrenching encounter with the ghost of her dead father.
Back on OtherWorld, the situation is grim. Fafnir accidentally releases the terrible Devourer of Souls, who nearly conquers the planet. In desperation, Tara changes into a dragon and allies herself with her nemesis, Magister. They defeat the Devourer, and Tara hurls Magister into Limbo, hopefully forever. Meanwhile, the Empress of Omois has discovered that Tara is her niece and heir. She insists that Tara come live on OtherWorld for good. If Tara refuses, it will mean war. This is the exciting sequel to Tara Duncan and the Spellbinders and is sure to captivate young readers for hours of excitement and adventure!
