The Enforcers — Gail Daley

This is novel about second chances.  Mix a Shoot 'em up Western with Science Fiction, Victorian Steampunk, add a little Mystery and a dash of Romance… Chloe and Caleb are two people who have been thrust into a deadly game of cat and mouse. Chloe is a former assassin for hire who is trying to reinvent herself as an investigator in the bustling metropolis of Junction City. Her first case proves to be far more complicated than expected, she finds a deceased Samuel Adams with a wicked knife sticking out of his groin - and all fingers point to her. Caleb Jones is an Enforcer for the City States on the Forbidden Colony planet of St. Antoni, hunting a serial killer. When he arrives in Junction City, he meets Chloe, and must decide if she is the killer he seeks - or the woman who can change his life.
