BOY WHO LOVED OCEAN by Tyree Campbell

Timothy Kline and his parents have moved from Earth to Arquid, settlers along with a few other families. Timothy is the youngest in his class. Alone and friendless, he seeks solace at the seashore, where he finds a friend. But she’s not like other girls. She knows his thoughts before he does. And there’s something he has to learn about himself. She can teach him—if she lives long enough.
