The Creep — Susan Dodson

After her babysitting charge, ten-year-old Annie, is attacked by a child molester, Sabrina Russell decides, in spite of her shyness, to act as a police decoy to lure the man who has been accosting children in the streets of Pittsburgh.

Brina wasn't listening when her favorite baby-sitting charge, Annie, started talking about the man outside the library. She was thinking about her boyfriend, Paul, and the lonely summer that stretched ahead without him. Anyway, Annie was an overly imaginative ten-year-old; she loved to tell stories and get attention.

After Annie was attacked, Detective Wallace tried to tell Brina that it wasn't her fault. So far no one had been able to stop the man who was molesting children in the Pittsburgh area.

Grandad was frightened. He wanted to take Brina away to the country until the man was under arrest. He tried to tell her gently what she already knew: at close to sixteen, she looked about twelve. She was painfully shy with kids her own age, and usually alone. She was a perfect target for the child molester.

Mom agreed with grandad. She wanted Brina to forget the whole things as quickly as possible. But Brina couldn't forget. When her fantasies of revenge subsided, she came up with a bold plan, that led her into danger--and caused her to change in remarkable, thought-provoking ways.
