When Casey Vice was eight years old, her father, a Police Captain who founded Saturn City's Criminal Intelligence & Organized Crime Unit, and her mother were murdered in front of their home. Orphaned and left with unanswered questions, Casey and her siblings narrowly escaped death, but not the scars the horrific ordeal seared into their innocent minds...

Fifteen years later, Casey, now a detective in the CI/OC, receives an invitation too dangerous to accept, yet too good to simply dismiss: a personal invitation to meet Shawn Anderson, the head of Saturn City's mafia himself....at his private estate.

She warily accepts the invitation and is faced with the gruesome revelation about her tragic past and an ultimatum that puts a million-dollar bounty on her head. As every con and killer in Saturn City's seedy underbelly looks to collect, Casey is propelled on a collision course with Saturn City's criminal regime-undaunted and determined to show everyone in her path why she is "The Spitfire of Vengeance."
