Don't call this mermaid "little"—call her "captain," unless you want to walk the plank.

Mary is in love with the so-called prince of Charles Town, except he doesn't love her back. Which is inconvenient. Since she's a mermaid, being brokenhearted means she'll—poof!—turn into sea-foam.

But instead, Mary finds herself pulled out of the sea and up onto a pirate ship. To survive, she joins them. But Mary isn't willing to just sing the yo-ho-hos. She wants the pirate life, all of it, and she's ready to make a splash . . . by becoming captain. But when Blackbeard dies suddenly, Mary has a chance to become so much more: Pirate King . . . or Queen. She won't let anyone stop her—not Blackbeard's cute son, not her best friend from back under the sea who's having a bit too much fun with his new legs, and certainly not everyone who says she can't be a pirate just because she's a girl. She may not be the best man for the job, but she'll definitely prove that she's worth her salt.
