The daughter of a local police detective, fifteen-year-old Ryann has spent most of her life studying how to pull off the most gruesome murders her small Colorado town has ever seen. But killing is only part of it. Ryann enjoys being the reason the cops are frenzied. The one who makes the neighbors lock their doors and windows on a hot summer’s day. The one everyone fears but no one suspects. Carving out her own murderous legacy proves harder than she predicted. Mistakes start adding up. And with the police getting closer, and her own father becoming suspicious, Ryann has to prove once and for all that she’s smarter than anyone else—or she’ll pay the ultimate price.
