Teen Novel Drama/Romance

Help me, please!

I read this book in the mid-early 2000's and cannot remember the title or author. I remember that it was about a teenager who moves and lives in a little bungalow/shack over the water and there is a surfer who sleeps on her roof because he is homeless. They are pretty close in age. They befriend each other and later they realize that he is her long-lost brother who was kidnapped when they were young. It mentions a red ball from their childhood, which is one of his only childhood memories. This girl also dates a super wealthy boy from across the pier and one of her friends struggles with anorexia.

I know that all makes no sense, which is why I can't find it.

Help me figure this out PLEASE!
