Have you seen this girl
(Book)

"Another girl has gone missing in Cardinal Creek. Sid knows their dad didn't do it--this time. He's currently serving a life sentence for the five girls he murdered ten years ago. Girls whose bodies he dumped into the lake. The same lake where June Hargrove was just found. And while Sid's dad couldn't have done it, suspicion is now directed at Sid. The only person who doesn't suspect Sid is the new girl, Mavis--as long as Sid doesn't let her find out about their past. But Sid has another secret: They're being haunted by the ghosts of the five girls their father killed. Except now there are six. And unlike the others, June isn't content to just whisper in Sid's ear. She wants them to find out who's killing again, especially as another girl goes missing. If Sid wants any chance of solving the current disappearances, they're going to have to face what their father did--or risk being haunted forever"--,Publisher's description.
