Wanted: Effective killer. Training provided. Kaden Rivera expected another dull shift at the restaurant. Instead, the 23-year-old left wearing her own blood. An armed robber had attacked. Kaden surprised everyone, including herself, by knocking him out. An impressed businessman offers a gig as an assassin. The side job was supposed to be simple. And it was, until her colleagues start dying. The boss is useless, and police aren't an option. Her only help is her best friend and a new AI mouse that he dubbed her "assistant." While still completing assignments, she plummets deeper into the criminal underworld-without her consent. Her only choice is to claw her way out.
