Whiton University unravels the night a star-athlete is murdered, kicking off a spree of social media slayings that force students to uncover the truth behind the school’s hidden secrets and the horrifying meaning of an exclamation point.

An unconventional thriller that takes place over three summers — 1993-95 — in a small Texas town when a beautiful popular teen, Kate, is abducted and, seemingly unrelated, a girl, Jeanette, goes from being a sweet, awkward outlier to the most popular girl in town and, by ’95, the most despised person in America.

Dusty Rhodes is new at Jefferson High, and she sticks out like a… well, a cowgirl. Dusty is a real cowgirl from Texas. Her parents are in the U.S. Army: her mother a helicopter pilot and her father a Special Forces Army Ranger. At first, Dusty is an outcast, but eventually she makes friends with a group that includes Savanah, a girl whose father was killed while fighting in Iraq three years earlier. Even though Savanah is kind of Goth and Dusty is all cowgirl they have a special connection and they bond. Dusty gets the school to agree to an Equestrian Drill Team and she enlists her new city slicker friends to join the team. As Dusty and the team practice, Dusty deals with the fears that come with her mother fighting in Afghanistan.
