Red Rider

A grieving father - known to the reader only as Teacher - takes on a new identity after the brutal murder of his teenaged son. Masquerading as a substitute teacher, he tracks down the killer - a high school senior - and methodically builds a web to entrap him. Teacher does not desire simple justice or death for the killer; he wants the killer to endure what his son endured. But Teacher's plan takes a life-shattering turn when he must save his son's former girlfriend from the clutches of the brutal MS-13 gang. A taut, suspenseful thriller, Red Rider explores the depths of revenge and the strength of human bonds.
