A series of books at various reading levels are publishing to coincide with the Walt Disney Animation Studios' Spring 2016 film release of Zootopia that follows the adventures of a fast-talking fox who is forced on the run when he's framed for a crime he didn't commit, and Zootopia's top cop, a self-righteous rabbit who is hot on his tail. When both become targets of a conspiracy, they're forced to team up and discover that even natural enemies can become best friends.
