Tales from The Compass Series by Dru Wellington

Aaron will do anything to save his family from being thrown out of their home. Anything. By day, he sings his throat raw busking, and by night, he uses his coin to gamble--cheat--wealthy men at the pier tavern. It looks like he might succeed too . . . until he bets against pirates. Soon, Aaron finds himself indebted to two men—a pirate prince with a sinister smile and more sinister secrets; and Captain Bjorn, whose deep brown eyes and disarming smile make sinister seem . . . sweet.
