The Caretaker by Marcus Kliewer

EXCITING OPPORTUNITY:
Caretaker urgently needed. Three days of work. Competitive pay. Serious applicants ONLY. 

Macy Mullins can't say why the job posting grabbed her attention--it had the pull of a fisherman's lure, barbed hook and all--vaguely ominous. But after an endless string of failed job interviews, she's not exactly in the position to be picky. She has rent to pay, groceries to buy, and a younger sister to provide for. 

Besides, it's only three days' work... 

Three days, cooped up in a stranger's house, surrounded by Oregon Coast wilderness. 

What starts as a peculiar side gig soon becomes a waking nightmare. An incomprehensible evil may dwell on this property--and Macy Mullins might just be the only thing standing between it, and the rest of humanity.
