Of all of the naughty, mischievous, disrespectful, and downright horrible things that children can be, a badling is perhaps one of the worst. Badlings abandon books without finishing them, leaving their characters sad and lonely-not to mention angry. Meet Bells, Peacock, Rusty, and Grand, four ragtag friends convicted of this monstrous crime. As punishment, they get sucked into a book of unfinished stories, whose patchwork pages they must traverse...and read to the end this time.

When an ancient book capable of summoning a demon is stolen from heaven, Narius, a young and not so bright angel of knowledge, is cast down and ordered to destroy it. If he fails, he can never return to his blissful life as a lazy library guard. Fortunately, to aid him in his quest, Narius is accompanied by the Codex, a theoretically holy book, who sprouts terrible courtship advice like a cheap fortune cookie. Upon arrival to the world below his, Narius is tricked into helping Emily, a greedy sorceress in a bit of a pickle, trying to deal with a hungry dragon. Together, the human and the angel must overcome enchanted apples, evil elves and the impoverished dragon or risk watching their world burn.
