I read this book when I was a teenager in the early 80’s but it is probably older than that. It was about this guy who would occasionaly see this girl and I think her name was Jenny. Everytime he would see her she appeared older than she should be, I think she was trying to grow up faster to be with him? At the end of the book she died in some kind of hurricane or something at a light house. I think there was a movie too. Sorry if this is too vague but this has been driving me crazy!
Thanks
