The Kill Lock

Banished for their crimes, four robots are bound to each other's fates in this sci-fi graphic novel. Each found guilty of an irredeemable crime, four robots find themselves banished from their home world and bound together by the Kill Lock–a programming link that means if one of them dies, they all will. Now a soldier, an addict, a murderer, and a child find themselves forced to protect each other while in search of a cure to survive. Their only clue is a bot known as The Axial, supposed to be the creator of the Lock and keeper of its secrets.
