Boundless — J.D. Cunegan

A little more than two years before the events of Bounty, Jill Andersen makes a life-altering decision. But this decision comes with consequences she didn't foresee, and her first night as the vigilante Bounty winds up being something for which she was wholly unprepared.

A crisis of faith eventually gives way to certainty: both in terms of discovering who killed a young man named Johnny Ruiz and in terms of coping with the latest change in her own life.

Along the way, Jill defies death and discovers just how deep the city's corruption runs. But will she survive the experience long enough to decide if a life of vigilantism is for her?
