"After a girl is killed by her ex-boyfriend in a school shooting, her two best friends attempt to memorialize her in a town economically dependent on the shooter's family"-- Provided by publisher.

Beck and Vivian never could stand each other, but they always tried their best for their mutual friend, Cassie. Then Cassie is killed at school by her ex-boyfriend Nicholas, the teen heir to the Bell Firearms fortune. After the town moves on from Cassie's murder too fast, Beck and Vivian finally find common ground: vengeance. They memorialize Cassie by secretly painting murals of her around town, a message to the world that Cassie won't be forgotten. When their murals catch the attention of a podcaster, they become the catalyst for a debate that Bell Firearms can no longer ignore. With law enforcement closing in on them, Beck and Vivian hurry to give Cassie the closure she needs-- by delivering justice to those responsible for her death. -- adapted from jacket
