He was under no illusions about who his companions on this journey were. Shaved heads, neck tattoos, bulging biceps, scars, noses that had been broken too many times - these were hardened men who had committed crimes serious enough to warrant a stay in Long Bay. And he was one of them. Riley Jax, convicted murderer. Once a promising engineer in the army, he lost everything in a single night when he killed a man - an act he cannot remember. It's a devastating gap in an otherwise perfect memory. Now he's facing a new life, one behind bars, where he has to learn a whole different set of rules and only the toughest survive. And as a series of deadly bombings rocks the outside world, the only man who might be able to find the truth behind the conspiracy... is on the inside.
