Graveyard of empires
(Book)

"For thousands of years, Afghanistan has been the rock that generations of would-be conquerors have perished on. What chance does one man stand in this place? So when ex-SAS major Ben Hope hears former bounty-hunter, Madison Cahill, needs his help he knows it will test him to his limits -- and beyond. As the borders slam shut, he must trace his friend before the new regime does. His only lead? An ancient lost city founded by Alexander the Great and rediscovered by Madison's archaeologist father. The mission will take Ben back to a place he thought was firmly in his past, back to someone he can never leave behind - and back to some old comrades. Among these is SAS man turned assassin, Jaden Wolf. Wolf has come to Afghanistan with his own agenda and knows as well as Ben that the conditions they face may prove as lethal as their enemies."--Publisher.
