Forbidden Love: A princess' temptation

It all started with a game. A game of truth or dare that had them falling for each other even though they were from different social ranks.
Katherine was a princess and he was a pirate. They were from two separate worlds and the idea of them being together was entirely forbidden and frowned upon.
Katherine hated pirates and the very first man she had kissed and found insanely attractive turned out to be one. She could feel her skin crawl as she looked at him...
Maybe he was different...or maybe not ..
Katherine had never been so conflicted in her life. The captain seemed to effortlessly mess with her thoughts and emotions.
......
Captain Leon Jones Calabran was a pirate whose heart belonged to his ship but one unplanned kiss with a mysterious lady threatened to change that.
However, he was quite confident that his life was going to remain the same since the chances of running into her again were pretty slim.
He was to leave the kingdom soon but he received the shock of his life when he soon found out that she was a princess.
A princess he was supposed to get to safety and spend a couple of months with!
Her clear ocean blue eyes effortlessly drew him in and it was
enough for him to know that he was in for the longest voyage of his life.
She was literally a walking temptation and he was doomed to think he could resist her!
....
What happens when Katherine finds out that she is not entirely human and that it seems to set two mysterious men on a relentless journey to capture her heart.
Could she choose the dashing human captain or one of the two tempting mermen?
