A Kiss in the Wind (Romancing the Pirate #2)
Jennifer Bray-Weber

Pirate captain Blade Tyburn is not pleased to find the letter he's been waiting for is missing. He's even less pleased when he discovers the thief is a raven-haired beauty who bewitches his senses and muddles his thinking. The note gives the location of a silver-laden ship that'll make his fortune; Blade must find it, and if that means bringing Marisol along on the voyage, so be it.
Marisol believes Monte sails on the very ship Blade is to meet and strikes a deal with the handsome rogue. If he will give her passage to her brother, she will give him the exact location he needs. And both will get more than they expected...
