Brian Keene 
With Teeth 

For a group of middle-aged friends, the trip into the forest was supposed to be simple. All they had to do was find a place to set up their criminal enterprise, and all of their financial problems would be solved. But now, night is falling, and with the darkness comes something else. Something fast. Something ferocious. Something… with teeth. From best-selling, award-winning horror writer Brian Keene comes a vicious new novella WITH TEETH.
