Full Brutal by Kristopher Triana
Winner of the 2019 Splatterpunk Award for Best Horror Novel
Kim White is a very popular cheerleader. She's pretty, healthy, and comes from a well-off family. She has everything a girl of sixteen is supposed to want. And she's sick to death of it.
In search of something to pull her out of her suicidal thoughts, she begrudgingly decides to lose her virginity, having heard it's a life-changing event. But Kim doesn't want to do it the same way her peers do. She seduces one of her teachers, hoping to ruin his life just for the fun of it. This starts Kim on a runaway train of sadism, and she makes every effort to destroy the lives of those around her. But soon simple backstabbing is not enough to keep her excited, and she nosedives into sabotage, violence, and even murder.
When Kim finds out she's pregnant with her teacher's child, a new madness overtakes her, and she realizes there's only one thing that will satisfy her baby's hunger . . .
