The Lab is a young adult science fiction action novel by Australian writer Jack Heath.

Six is an agent of a vigilante organization called "The Deck" which survives by attacking ChaoSonic subsidiaries that are acting unethically, arresting the people involved and then selling off their assets.

Only the King of Hearts, who saved Six from the Lab as a child, and is now his boss, is aware of the fact that Six is a superhuman developed by ChaoSonic.

Six and King keep this a secret, as the Spades, another division of the Deck, would imprison Six if they knew he was a ChaoSonic creation, in case he was a threat.

[1] Agent Six of Hearts was created by designer DNA and 'born' in The Lab, a division of Chaosonic, along with his two clones Kyntak and Sevadonn.

At the age of thirteen Six began working for The Deck; a law enforcement organisation founded by King of Hearts.

Being created from designer DNA and hence 'superhuman'; Six is able to run faster (up to 50 kilometres per hour), jump higher and is stronger than any of the other agents at The Deck.

Six is described as having black hair, blue eyes, sharp profile, white teeth, thin fingers and pale skin.
