Rescuer's Reward. Sea Mage Cycle

A captain in debt, a princess in peril, and a fate that neither can foresee. All Jason ever wanted was to sail the Azure Sea as a merchant ship's captain. But money problems have him up to his eyeballs in debt, and if he doesn't return to port with the gold, his dreams will be dashed forever. So when the princess of a far-off kingdom is kidnapped by pirates en route to her wedding, Jason merrily takes up the chase, staking his future on the reward for her safe return.
Yet the competition for the princess proves fierce, and Jason soon learns that there are far more powerful forces behind her kidnapping than any of them realize. And though Princess Julietta has no qualms about marrying for political advantage, the last thing she wants is to be a mere trophy in a different sort of game. As duty, desire, and destiny clash, only one thing is certain: they both must risk everything to earn the ultimate reward.
