Divine Madness

This is a book in the bestselling British series CHERUB. The series is based on a group of children that the government funds and sends on missions all around the world. They're trained in martial arts, weapon handling, espionage, computer skills and trickery. There are lots of CHERUB agents, but the series mainly follows James Adams, his younger sister Lauren Adams and their group of close friends. This particular book is when CHERUB discovers a link between eco-terrorist group Help Earth and a wealthy religious cult known as the Survivors, James, Lauren and a new agent named Dana are sent to Austraila on an infiltration mission. It's one of the toughest missions so far. The Survivors outback headquarters are completely isolated, and the cult's brainwashing techniques mean that the kids are under massive pressure to conform. This is an excellent series and a great book.
