A grieving father, a brutal overdose, a silver revolver-and nothing left to lose.

Slim Purdoux was once just another ex-con trying to go straight. After doing time in Texas for drugs, he landed a miracle job as a book editor in San Francisco. But fate had other plans. When his only son dies of a fentanyl overdose-and Slim is mistakenly caught up in a mass shooting-the weight of grief, rage, and injustice drives him to a dangerous edge.

Now hunted by cops and haunted by loss, Slim returns to the only thing he was ever good at: shooting fast and shooting straight. Armed with a custom silver revolver and a lifetime of regret, he plunges into the violent heart of the American underworld to settle the score with the cartel that killed his son.

What follows is a gritty modern western wrapped in a blood-soaked crime thriller, where vengeance is a drug stronger than anything on the streets-and justice is a bullet away.

Will Slim survive the war he starts? Or will the truth about his past destroy him before he even gets close?

The Silver Revolver is a feverish, unflinching dive into the darkest corners of vigilante justice, addiction, and the price of revenge.
