Surface by Jody Morse

With her new job as an Ocean Grove Junior Lifeguard, Felicia Parks’s summer was supposed to involve cute boys and fun in the sun. While her summer did bring cute boys, it also brought something else, too — a girl who looks eerily like the sister who she thought she’d lost six years earlier in a tragic accident. But how could that be possible when Scarlett was supposed to be dead? Felicia soon comes to find that the captivating song she heard the night of Scarlett’s death may explain everything… and is even deadlier than she’d realized.
