Eleanor and Park by Rainbow Rowell

Park is popular, Eleanor is not.  Park is athletic and sociable, Eleanor is withdrawn and clumsy.  Almost against his will, Park is drawn to Eleanor's strangeness and he begins to share his playlists with her.  Their love of music draws them into a friendship that could be more.  But Eleanor needs help, there's a good reason why she is so strange.  Park steps outside his comfort zone to be a good friend to Eleanor and finds strengths he didn't know he had. Although there is some strong language, this book was hard to put down.
