Fourteen-year-old Jess Tierney is an exceptional teenager: athletically gifted and academically brilliant. Bored at her conventional Dublin school, she is thrilled to be offered a place at PEP Academy, the training ground for the top secret PEP (Planet Earth Protection) Squad. During her first term Jess quickly makes friends with her room-mate, extreme-sport loving Emily Harris, and the Sykes twins, Ben and Matt. Together they start to learn the skills they will need to become world-class spies, like lock-picking, making disguises, abseiling, foreign languages and combat training. At the end of their first-year the teenagers are promised an easy first mission. But then they find out they have to infiltrate a Bavarian castle and steal a sample of a deadly virus that could wipe out all of humanity. Faced with armed guards, a complex security system, an evil genius and a traitor in their midst the trainee spies must save the day or die trying. This is set to be the next big thing in adventure fiction for pre-teens!
