Martina's hard-hitting, uncompromising and haunting writing is in a genre all its own - no one writes like Martina. 2013 sees the publication of this, her twentieth novel, and with REVENGE she is back and better than ever.

* Don't miss GUILTY, the brand new novel from Martina Cole. Out now. *

He thought he was invincible. He was wrong.

REVENGE by the 'undisputed queen of crime writing' (Guardian) and Sunday Times No.1 bestseller Martina Cole is an unflinching novel that exposes a world that many would rather ignore...

Michael Flynn is untouchable. He's the boss of a dangerous empire, the biggest the criminal world has ever seen. No one crosses him, no one gets in his way, and everyone does what he says - including the law.

But you don't get to where Michael is without making enemies. Someone is out for revenge. And it's best served when least expected.
