I just read "Joe the Barbarian" by Grant Morrison and Sean Murphy and highly recommend it. Published by Vertigo and all 8 issues are 99c each on Comixology.
EDIT: Just realized the title might throw you off a bit... the story is about a diabetic boy who goes too long without his medication and starts to hallucinate that his toys have come to life and his pet rat is a six foot-tall warrior. He embarks on an epic quest that takes place simultaneously in his house, and a fantasy realm that mirrors aspects of his house. For instance, he turns on the water in his tub and it overflows onto the stairs. In the fantasy world this becomes a waterfall. The whole 8-issue story is him trying to get downstairs to get medicine or call his mom for help.
