New York Times bestselling author of The Unwanteds brings us an epic animal adventure story perfect for fans of Pax and A Wolf Called Wander. The only good cat is a fed cat. Clarice, a young ship mouse, knows this to be true. She and her brother, Charles Sebastian, were taught to be careful―as all mice are―but caution is no match for the sea, which took their mother, and it is certainly no match for Special Lady, the horrid cat who ate their sister.
