Class A, published as The Dealer in the United States, and as The Mission for 5000 prints, is the second book in the Robert Muchamore's novel series CHERUB. It continues the story of teenager James Adams and his fellow CHERUB agents as they try to bring down a drug gang led by Keith Moore. The book was originally to be called Drugs, Cars and Guns, but this was changed so as to sound more appropriate for children. It received generally good reviews although not as many awards as its predecessor, The Recruit. It is followed by Maximum Security.
It was released in the United Kingdom by Hodder Children's Books on 14 October 2004, and as The Dealer by Simon Pulse in the United States on 23 August 2011.
