Looking for a particular book.

I am looking for the book about a girl who is at an open air market and runs into this handsome man who has blue eyes. They talk and he gives her a gold coin. She doesn't see him again and goes on this adventure where there is this guy who is annoying but is there for her. At the end of the book, she realizes that this blue eyed guy and the brown eyed guy are one and the same. He hid his eyes so she wouldn't recognize him and he could protect her.
It's a christian fiction book. I don't remember the title or the author.
