Battleground by Chris Ryan
You wake up in a dark room with no idea where you are. You are gagged and forced into a waiting truck. You have done nothing wrong. What would you do? Fourteen-year-old Ben travels to Pakistan on a school exchange programme. Ben and his Pakistani host, Aarya, find themselves in the wrong place at the wrong time. They see something they're not supposed to and are kidnapped by some strange men. Caught up in a terrifying planned terrorist attack that could destroy Southern Afghanistan, killing thousands, Ben and Aarya are dragged through the most terrifying battleground in the world.
