No one cares that you cured cancer if you also cloned a horde of dinosaurs and let them rampage down the street. Supergenius and quasi-villain Rex must stop her twin brother, definitely-a-villain Last Dance, from taking over the world. If she fails, the real heroes will lock them both up for good. “Thoroughly entertaining and utterly delightful.” —Publishers Weekly, Starred Review “Raney's debut is a blast [and] inventive as all get out.” —Booklist, Starred Review
