Any title you select is likely to be only temporary. Your publisher will put a title to it which is most likely to help sales of the book. Trust the publisher's judgement - he will know the market.
Mariposa county is in California, is there a connection? I like this name, it is enigmatic and unusual so would arouse interest. It would need to be connected with the story in some way though.
Without a synopsis of the book, one cannot suggest a title for it. Although, saying that, you could look within your own work for an inspiring title - it could be the name of the protagonist.
