An Idle King by Andrew Paterson

Imagine fighting a war no one wanted you to win. Imagine never wanting to leave. Afghanistan has been abandoned by the international community. Left to the ravages of warlords and mercenaries, vying for dominance over the new Silk Road. For Callum King, a former officer who was discharged from the army, his past remains very much tied to that forsaken place. When he receives an offer from one of his former soldiers to work for a private security company in Kandahar, the contract represents an opportunity to make amends for his failures as a soldier and a leader. But the cost would mean walking away from a family that he’s tried so hard to put back together. An Idle King is a modern retelling of an ancient story about lost soldiers who can never go home.
