Title: Skulduggery Pleasant
Author: Derek Landy
When a not-so-innocent twelve-year-old girl named Stephanie inherits her eccentric uncle’s estate, she must join forces with Skulduggery Pleasant, a skeleton mage, to save the world from an ancient evil.
Meet Skulduggery Pleasant
— as well as ally, protector, and mentor of Stephanie Edgley, a very unusual and darkly talented twelve-year-old.
These two alone must defeat an all-consuming ancient evil.
The end of the world?
Over his dead body.
