When his wife's past comes barging through the doors - four armed men sent to abduct her, Xan's world snaps from its orbit. While one intruder narrowly escapes with her, three do not, one of whom he briefly spares to extract an answer on her whereabouts. Yet his methods lead to his arrest, further testing his glue with disastrous results that lands him seven years in prison. Xan's now a free man, about to embark on a journey into the highlands of Turkey to either save his wife or avenge her death. Yet a slew of obstacles stand before him, such as acquiring the money and firepower needed, and smuggling those weapons across several borders, along with gathering his former squad of now middle-aged men, and entering a clannish land in the rugged mountains of Kaçkar, where a small army surrounds the crime lord who kidnapped his wife. But it'll all mean nothing without an exit strategy from Turkey, and the only man who can help is his father - a retired Army colonel and an imperious figure whom he hasn't spoken to in ten years. All the while, he recalls the pivotal events in his life that led to this moment, from his violent coming-of-age on the streets of New York to his tours in the military as a special ops soldier, from his idyllic life in the suburbs with his wife to his time in prison where he battles not only to survive, but his own demons as well. And though Xan insists that his mission is one of rescue rather than vengeance, he must confront the probability that Kerinna's no longer alive. SEMPER is an epic adventure that spans three decades in the life of one man, and his quest to find his abducted wife.
