Waste by Andrew F. Sullivan

Larkhill, Ontario. 1989. A city on the brink of utter economic collapse. On the brink of violence. Driving home one night, unlikely passengers Jamie Garrison and Moses Moon hit a lion at fifty miles an hour. Both men stumble away from the freak accident unharmed, but neither reports the bizarre incident.
Haunted by the dead lion, Moses storms through the frozen city with his pathetic crew of wannabe skinheads searching for his mentally unstable mother. Jamie struggles with raising his young daughter and working a dead-end job in a butcher shop, where a dead body shows up in the waste buckets out back. A warning of something worse to come.
Somewhere out there in the dark, a man is still looking for his lion. His name is Astor Crane, and he has never really understood forgiveness.
