Dora Madison Burge

For five friends, it was a chance for a summer getaway, a weekend of camping in the Texas Big Thicket. But visions of a carefree vacation are shattered with an accident on a dark and desolate country road. In the wake of the accident, a bloodcurdling force of nature is unleashed, something not exactly human, but not completely animal, an urban legend come to terrifying life; and seeking murderous revenge.

As firehouse Lt. Matt Casey deals with the fallout of his undercover work and Rescue Squad Lt. Kelly Severide struggles with a demotion, personal matters threaten the focus needed for the crew's daily life-and-death decisions.
