Secret Army

If you like Britain, history, spies and books where the main characters are teenagers, you'll like this book. Set in 1941, England is in war. After several desperate attempts to win the war against the Nazis, the government has finally decided to give Charles Henderson, a man not supposed to exist, a chance. A top British spy, only a few months earlier, his entire operation was compromised by a group of teenage children. His life was then saved by these same children, along with an incredible victory for Britain at the hands of the latter. Now, back in the world of pompous bureaucrats and crooked politicians whose most realistic experience with war is sitting in stuffy meetings while an officer covered in glittering medals announces war tactics that seem to be in a different language, Henderson's last chance to promote his idea of using child spies rests on one man. A particularly pretentious administrator,  Air Vice Marshall Walker married into his position and has accumulated a deep and abiding hatred for Henderson over the years, which began when Henderson punched him so hard he was in the hospital for two days. Now, it's up to PT, Rosie, Marc, Troy, Paul and Joel to save the beginnings of CHERUB (Charles Henderson's Espionage Research Unit B) before the malicious Walker brings the group crashing to the ground.
