A swashbuckling story of two very different cat brothers and their adventures at sea.

Anton and Cecil are as different as port and starboard. Cecil, stocky and black with white patches, thirsts for seafaring adventure. Slim, gray Anton prefers listening to the sailors' shanties at the town saloon. One day when Anton goes to the harbor, he's taken as a ratter on a ship bound for the high seas. Cecil boards another ship in hopes of finding Anton. What begins as a rescue mission turns into a pair of high-seas adventures. Anton takes on a fierce rat, outwits hungry birds, and forges a forbidden friendship, while Cecil meets dolphins and whales and finds himself in a pirate raid.

On an ocean as vast as the one Anton and Cecil have discovered, will they ever see home--or each other--again?

Includes a sneak peek at the next adventure in the series, Anton and Cecil: Cats on Track.
