From the award-winning creator of Have You Seen My Dragon? and Have You Seen My Monster? comes a broken-down ship, a loose button and a little pirate's brilliant idea: Let’s SWAP!

A broken-down ship. A loose button. An idea: Let’s SWAP! In this first book of bartering and mental arithmetic from the acclaimed author/illustrator of Have You Seen My Dragon? and Have You Seen My Monster?, a pint-sized pirate sets out to help a sea captain repair his decrepit vessel. One button for three teacups. SWAP! Two teacups for four coils of rope. SWAP! And so it goes, until the little swashbuckler – through simple sums – secures sails, anchors, a ship’s wheel, and more… But can he really barter his way to a nifty new ship for the captain in need? Steve Light’s exquisite, intricate pen-and-ink illustrations, punctuated with brilliant blue, anchor this clever tale of commerce, ingenuity and friendship.
