Loki: A Bad God's Guide to Being Good by Louie Stowell

Wry, witty and very funny diary-style story packed with doodles and comic strips about the frustration trickster god Loki feels at having to live trapped in the body of a weedy eleven-year-old boy. After one trick too many, Loki is banished to live on Earth as a "normal" school boy. Forbidden from using his AWESOME godly powers, Loki must show moral improvement.
