The second instalment in Andy McNab's Street Solder Series.

HOW DO YOU FIGHT AN INVISIBLE ENEMY?

A high-speed chase through the backstreets of Lagos and an unexpected bomb explosion in the jungle – it’s all in a day’s work for soldier Sean Harker.

Looking forward to a well-earned break back home, Sean and his platoon fly back to the UK, only to find themselves fighting their way out of an airport hostage situation, and the country on high terrorist alert.

Barely escaping with his life, Sean must now embark on a dangerous mission: to locate a deadly weapon, capable of destruction on a massive scale. . . a weapon no one will see coming.
