A bad god's guide to being good
(Book)

After one prank too many, trickster god Loki has been banished to live as a kid on Earth. If he can show moral improvement within one month, he'll be allowed to return to Asgard. If not? Eternity in a pit of angry snakes. School, fake "parents," and an eleven-year-old Thor's farts are pure misery. But when a bigger threat than Loki's mischief comes to Earth, Loki will have to decide whether he's really a villain, or if he might want to do the right thing for once.--,Publisher's description.

I, Loki, the mighty trickster god, have been banished by Odin to live on Earth as an eleven-year-old boy. To get back home I must... 1) Do good deeds (so tedious) 2) Go to school (so cruel) 3) Put up with Thor (so many farts). Wish me luck! Or don't. I care not for the opinion of mere mortals.
