Highway to Hell — Rosemary Clement-Moore

Maggie Quinn was expecting to find plenty of trouble with Lisa over Spring Break. Give a girl a bikini, a beachfront hotel, and an absent boyfriend, and it's as good as a road map to the dark side. But Maggie doesn't have to go looking for trouble. Trouble has started looking for her. One dead cow and a punctured gas tank later, she and Lisa are stuck in
Dulcina, Texas--a town so small that it has an owner. And lately life in this small town hasn't been all that peaceful. An eerie predator is stalking the ranchland.

Everyone in town has a theory, but not even Maggie's psychic mojo can provide any answers. And the longer the girls are stranded, the more obvious it becomes that something is seriously wrong. Only no one--not even Maggie's closest ally--wants to admit that they could have been forced on a detour down the highway to hell.
