Curveball The Year I Lost My Grip by Jordan Sonnenblick

Peter had it all until he blew out his arm pitching a game.  After surgery and physical therapy he learns he won't ever be able to play baseball again.  His grandfather, a professional photographer, takes him up to the mountains to snap photos of eagles.  Peter realizes there's something wrong with his grandfather.

I liked this book.  Teens need stories about family with parents or grandparents who are ill.  Told in a positive teen life.  I think this book would be good in any teen library.
