By August

Over the course of one Colorado summer, a boy investigates the hit and run death of his sister. With the help of a lost time traveler and his dog (which is a Lovecraftian monster gathering strength), he must find her murderer before being sent back home to New York in August.

Trigger warning: murder/death of a child discussed at length, alcohol use discussed at length as well as 'coming of age' issues. Some gore and violence, some language.
