The Robe of Skulls

The sorceress Lady Lamorna wants a skull-studded gown of deep black velvet, but her treasure chest is empty of gold. That doesn’t stop her, however — from kidnapping, blackmailing, and using more than a little magic to get what she needs. Will her plans be foiled by the heroic Gracie Gillypot, two chatty bats, a gallant (if scruffy) prince, the wickedest stepsister ever, a troll with a grudge, and some very ancient crones?
