'Your abilities as a Keeper allow you to open doors that others cannot.'
Imprisoned in the mythical world of Bellania, Charlie Keeper is at the mercy of Lord Bane's guards while her loyal friends have been sold into slavery.
When the Terrifying Edge Darkmount breaks into her cell, he promises to decipher the meaning of her mysterious pendant - and unlock the secrets of Bellania - if she will help him get revenge on Bane.
But can she trust him? The future of the realm relies on Charlie's special powers. Even if she escapes it may take more than she can summon to overthrow the evil lord - it may take an entire army . . .
