Skulduggery Pleasant by Derek Landy
On an ordinary day, in an ordinary town, an ordinary girl is about to make an extraordinary acquaintance----. She turned. When his hat had come off, his hair had come off too. In the confusion, all she had see was a chalk white scalp, so she turned expecting to see a bald albino - maybe? But, no. With his sunglasses gone and his scarf hanging down, there was no denying the fact that he had no flesh, he had no skin, he had no eyes, and he had no face. All he had was a skull for a head.
When Stephanie inherits her eccentric uncle's estate, little does she know that she's inheriting something along with it ; a life-or-death battle between good and evil. Fortunately for Stephanie, she also inherits a friend and ally that might help her make it out of this alive - Skulduggery Pleasant. With his dashing fashion sense, snappy wit, and fire-throwing abilities, Skulduggery is just the fellow to have along in a fight. So who cares if underneath the designer clothes he's just a skeleton?
