The Wild One
Losing ground in his fight against post-traumatic claustrophobia, war veteran Peter Ash has no intention of getting on an airplane--until a grieving woman asks Peter to find her eight-year-old grandson. The woman's daughter has been murdered. Erik, the dead daughter's husband, is the sole suspect, and he has taken his young son and fled to Iceland for the protection of Erik's lawless family.
Finding the boy becomes more complicated when Peter is met at the airport by a man from the United States Embassy. For reasons both unknown and unofficial, it seems that Peter's own government doesn't want him in Iceland. The police give Peter two days of sightseeing in Reykjavik before he must report back for the first available seat home... and when they realize Peter isn't going home until he accomplishes his mission, they start hunting him, too.
From the northernmost European capital to a rustbound fishing vessel to a remote farm a stone's throw from the arctic, Peter must confront his growing PTSD and the most powerful Icelandic snowstorm in a generation to find a killer, save an eight-year-old boy, and keep himself out of an Icelandic prison--or a cold Icelandic grave.

Nick Petrie
Few thriller writers manage to marry raw physicality with emotional depth the way Nick Petrie does. His novels aren’t just fast-paced—they hum with tension born from real-world scars. At the heart of his bestselling Peter Ash series is a veteran struggling to find peace in a country that doesn’t quite know what to do with him. Ash isn’t a hero in the classic mold—he’s restless, damaged, fiercely competent, and often alone. And it’s precisely this uneasy combination that makes him—and Petrie’s work—so compelling.
Peter Ash
He doesn’t seek out trouble—but trouble has a way of finding him. In a country bristling with tension, violence, and unseen threats, a former Marine with combat scars that won’t fade walks a fine line between survival and salvation. The Peter Ash series digs deep beneath the surface of the action-thriller genre, delivering not just explosive plots, but a portrait of a man trying to stitch himself back together in a world that rarely makes room for healing.
Peter Ash consists of nine books and series is set to expand with the upcoming release of one more book. The current recommended reading order for the series is provided below.
