Mothman

From publisher blurb:

You sit perched, watching the car lights get bigger as they come towards you. Instinct fires your nerves, trying to make you move so you won't be seen. Your brain overrides you impulses and you stay put. The car pulls over and the lights go out. Four teenage thrillseekers get out and turn on their flashlights. They've come looking for you. You can hear their jibes as they tease each other about being scared. Fear turns to excitement as you launch yourself from your perch. You give the teens exactly what they've came for, The Mothman!
