(Description nicked from B&N.com.)
“The rulers of tiny, impoverished Swansgaard have twelve daughters and one son. While the prince’s future is assured, his twelve sisters must find their own fortunes.
Disguising herself as Clarence, a sailor, Princess Clarice intends to work her way to the New World. When the crew rebels, Clarice/Clarence, an expert with rapier and dagger, sides with the handsome navigator, Dominick, and kills the cruel captain.
Dominick leads the now-outlawed crew in search of treasure in the secret pirate haven known as The House of Four Winds. They encounter the sorceress Shamal, who claims Dominick for her own—but Clarice has fallen hard for Dominick and won’t give him up without a fight.”
