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.

For a mouse, there is only one good kind of cat: a fed one. Clarice and Charles Sebastian were raised with their siblings on a trading vessel. They 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 the horrid ship cat Special Lady, who ate their sister. Soon, a shocking mutiny forces Clarice onto a dinghy with Special Lady and half a dozen hungry sailors, while Charles Sebastian remains on the ship with the mutineers and a flock of irate chickens. Being careful may have saved them in the past, but they'll need to grow bold if they are to survive . . . and find each other again. From the New York Times bestselling author of The Unwanteds comes an unforgettable adventure that's driven by perseverance, kindness, and hope.
