This review is from: CHERUB 5: Divine Madness (Paperback)
When CHERUB discovers a link between terrorist group Help Earth and a wealthy religious cult called the Survivors, the authorities want to know more. James, Dana and Lauren go undercover inside the Ark (a big armed building), posing as the three children of a divorced parent played by an ASIS (Australian Secret Intelligence Service) agent named Abigail to help discover the truth behind the Survivors. During the mission Dana gets a chance to infiltrate Help Earth but she ends up on a boat in the middle of the ocean with three skilled people, two of them armed and one of them brainwashed, all ready to bomb an Ign oil tanker just off the coast of India.
I found this book very interesting. I never knew it is possible to brainwash a person without knowing that you're brainwashed yourself! Very well described. Recommend it to everybody over 11.
