No Sanctuary - Richard Laymon

Rick would do anything for his girlfriend Bert. He'd even spend his vacation in the wilderness, walking the trails around Fern Lake. After what happened last time, it's the one place in the world he'd prefer not to go. But Bert is a woman with a passion for the outdoors - and a passion for other things too. Rick would follow her to hell and back - which is what he's about to do. Gillian is off on vacation too, only her idea of a holiday is a little weird. She likes breaking into people's homes while they are away and living there. Pity that this time she chances on the home of a serial-killer. The kind of guy who likes to take his female victims out into the wilderness for his fun. Rick and Bert are not the only ones heading to Fern Lake...
