Being a boy is tough enough--there are parents to please, forts to build, and pesky girls to battle. But when Finn finds himself confronted by an eyepatch wearing, dagger slinging rabbit, things are bound to get a little more complicated. Throw in a headless horseman and an evil, necromancing cousin, and Finn's in for the fight of his life. Guess history forgot to mention that there are some legends aren't legends at all--they're prophecies. And, as Finn's about to find out, he's right in the middle of a big one. If he hopes to survive, Finn's going to have to rely on the creatures that have haunted him for years, and learn that friends are often much more than meets the eye.
