The Wall and the Wing

A few, nicknamed leadfeet, are forced to forever spend their lives closer to the ground. But one night, a girl named Gurl — a leadfoot, an orphan, a nobody — discovers that she can do something much better than fly.

She can become invisible.

Along with a new friend, a boy named Bug, Gurl begins a quest that takes her on a wild ride through the magical city, all the way to the handsome but lethal Sweetcheeks Grabowski — the gangster who holds the key to Gurl's past... and the world's future.
