Code Black: Cut Off and Facing Overwhelming Odds:

'A fast-paced, thrilling account of British heroism, brave men surrounded and fighting against overwhelming odds. This is the real, sometimes shocking, and deeply personal story of modern warfare and PTSD.' Andy McNab

Trapped in an isolated outpost on the edge of the Helmand desert, a small force of British and Afghan soldiers is holding out against hundreds of Taliban fighters.

Under brutal siege conditions, running low on food and ammunition, he experiences the full horror of combat. As the casualties begin to mount and the enemy closes in, Evans finds both his leadership and his belief in the war severely tested.

Returning home, he is haunted by the memories of Afghanistan. He can't move on and his life begins to spin out of control.
