IT'S A CRUEL SUMMER Arrrr! All Sam wants this summer is to watch baseball, play video games, and read his favorite supernatural series. Too bad his cousin, Alex, is visiting from San Francisco, and now Sam's stuck playing tour guide to a kid he hardly knows . . . a kid who'd choose sailing camp over stealing bases any day. Then Sam and Alex find themselves swept up in an epic pirate adventure through the historic streets of Boston. With the help of a three-hundred-year-old ghost-pirate, they'll have to piece together the clues of a long-lost treasure map--and master a tricky sailor's knot--or risk becoming ghosts themselves! The cousins may not have much in common, but along the way they'll learn that some bonds, like some knots, are truly unbreakable.
