Phantom Limbs

"Otis and Meg were inseparable until her family abruptly moved away after the terrible accident that left Otis's little brother dead and both of their families changed forever. Since then, it's been three years of radio silence, during which time Otis has become the unlikely protaegae of eighteen-year-old Dara--part drill sergeant, part friend--who's hell-bent on transforming Otis into the Olympic swimmer she can no longer be. But when Otis learns that Meg is coming back to town, he must face some difficult truths about the girl he's never forgotten and the brother he's never stopped grieving"--Amazon.com.
