As the title states, long time ago I've read this fantasy (as far as I can remember) book and just recently it came to my mind and I want to reread it. I don't remember the name or how good it was, I just remember very few facts of the plot such as:

There seem to be two main heroes a man and a woman, supposedly from different tribes or factions or something like that. And they somehow end up on some sort of island with some people under their wing and they try to set up a life and end up falling in love with each other. That is as much as I can remember unfortunately.

I know the description is very vague, that's why my google searches weren't successful (or maybe I'm getting some facts wrong). Anyways, if you could point me in the right direction I would appreciate it very much. Thanks.
