Overkill — Uvi Poznansky

The last thing Ash expects when she lands in Clearwater, Florida is to be stalked by a troubled teenager. If that's not bad enough, she is caught in a shooting spree next to the nearby elementary school. The cops think it's an attempt at mass killing, but Ash wonders if the only victim was specifically targeted by the killer. Will she manage to identify him and have him arrested before he comes after her?
