Author's note: I obviously don't own either CHERUB of The Avengers, however much I wish I did.
The first couple of chapters are very CHERUB based, but the Avengers link will become clear very soon, so do give it a chance!
I hoped to try and make this story unique, so please enjoy!

CHAPTER 1

WHAT IS CHERUB?

CHERUB is a branch of British Intelligence. Its agents are aged between ten and seventeen years. CHERUBs are mainly orphans who have been taken out of care homes and trained to work undercover. They live on CHERUB campus, a secret facility in the English countryside.

WHAT USE ARE KIDS?

Quite a lot. Nobody realises kids do undercover missions, which means they can get away with all kinds of stuff that adults can't.

Skye Devlin pushed her way through the hordes of teenagers, keen to find some fresh air and respite from the music blaring through several large speakers. She stepped onto the balcony letting the night air was over her for a while before pulling out her buzzing smartphone.

1 NEW MESSAGE

It was from CHERUB's chairwoman Zara Asker, Skye opened it.

Firewall has been breached. Come to mission control ASAP.

"Shit", Skye swore, turning back and ploughing through the party before sprinting down several flights of stairs, sliding around in her socks then bursting through a door and out into the night. She would never ignore a SOS call from Zara, especially when Skye knew that with its information vulnerable, CHERUB was under threat.
