A positively ingenious story about a mysterious island, long-lost secrets, and a young girl's quest in the world of mad science, Linette Moore's debut middle-grade graphic novel, The Prisoner of Shiverstone, "is a good mix of fantasy, mystery, and action" (Horn Book). Eleven-year-old Helga Sharp is found unconscious in a drifting rowboat near the coast of Utley Island. Utley, as Helga finds out when she awakens in the hospital, is forbidden territory: It's a prison island to which the Mainland has exiled troublesome mad scientists for generations. Helga is questioned by the island's guards and though they're suspicious of her story, they agree to let her stay until they find her family. The truth is, it's no accident that Helga landed here. She is a keen inventor, but the Mainland is suspicious of all scientists and inventors.
