"A Mask of Flies by Matthew Lyons is a pulse-pounding crime horror epic about a criminal on the run, the deadly family secrets she unearths along the way, and the sinister monster from her past that has gotten a taste for her blood--and won't sleep until she's dead. In the grisly aftermath of a botched bank heist, career criminal Anne Heller has no choice but to return to her family's cabin - a secluded shack in Colorado's San Luis Valley, and the site of her mother's untimely death. Along for the ride are Jessup, Anne's badly wounded partner, and Dutch, the police officer she's taken hostage. As they wait for help, Anne discovers strange relics from her mother's past and begins to unfold the mystery of her childhood at the cabin. Then Jessup goes missing, only to turn up dead. Anne and Dutch bury her friend, but that night, he comes back and knocks at the cabin door. Not a dream, not a hallucination, but not exactly Jessup, either. Something else. Something wearing her friend's face. Something hungry..."-- Provided by publisher.
