[TOMT] [BOOK] A novel about a baby who is found washed up on a beach

I was reminded of book by the novel 'The Light Between Oceans', but the book I'm looking for came out prior to 2008 so it's definitely not that.

The plot is that a baby girl is found washed up on a beach, and is taken in by townspeople. I think they name her Aurora. I think it's an unusual community, maybe based around fishing, and maybe somewhere in the Arctic circle with midnight sun. The girl grows up to not fit in with the community. I don't remember any more of the plot.

I read it at some point between 2003 and 2007, but I don't know when it was released.

Thank you!
