Chad Zunker

Chad Zunker writes fast-paced suspense shaped by legal workplaces and ordinary people forced into impossible choices. Based in Austin, Texas, he earned a journalism degree from the University of Texas and spent years at a large corporate law firm before publishing The Tracker, the novel that launched his Sam Callahan series. Thomas & Mercer published All He Has Left in 2023. Its central figure, Jake Slater, is grieving his wife when an estranged-family reunion precedes the abduction of his daughter Piper. Evidence then turns suspicion toward Jake, leaving him to protect his child while questioning what he knew about his marriage and the people closest to it. Zunker keeps the story tightly focused on family loyalty, hidden identities, and the pressure of being disbelieved. The novel stands apart from his Sam Callahan and David Adams series, but it uses the same blend of legal tension and rapid reversals. All He Has Left shows Zunker's recurring interest in protagonists who must think clearly after familiar institutions stop offering protection.
