Escape from Hat
(Book)

"We all have good luck and bad, courtesy of our very own lucky rabbits and black cats. Most people never even notice them. Cecil Bean had certainly never noticed his villainous cat, Millikin, or his devoted rabbit, Leek. At least not until Millikin hatched a deliciously evil plan to have Leek vanish within a magician's hat, leaving Cecil with no good luck at all. Thrown into a shadowy, perilous world, Leek will stop at nothing to return to his boy--even though no rabbit has ever escaped the land of Hat before. To do so, Leek must sail across the Great Ink, travel beyond the Jungle Prime Evil, brave the Grottos of Ill Repute, and breach the very seat of all bad luck--the dark fortress of the black cats itself. Meanwhile, as cat and rabbit battle for control of his fate, Cecil comes to realize that sometimes in life, with your back against the wall and all odds stacked against you, the only solution is to roll up your sleeves and make your own luck, all by yourself, from scratch." -- publisher description from jacket.
