Artemis was recruited by Cherub, but they don't know about his shady background. He tries to fit in, because he has no other way to look after the twins, after his parents died in a plane crash. He expects a happier life, but when Jon Spiro escapes from prison, he gets a lot more than he bargained for.

This happened after the first AF book. Most of you possibly can't imagine Arty as an Cherub-agent, huh? Then what could I possibly come up with? Find out!
