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.

When a madman sets his sights on her, Georgia, the only person in the world who can become invisible at will and the Richest Girl in the Universe, must confront a pack of laid back vampires, a living lion of stone, a candy-loving sloth, and the Second Richest Girl in the Universe to survive.
