Tomorrow, the killing - Daniel Polansky

Dark, violent, and shot through with corruption, TOMORROW, THE KILLING
is a fantastic successor to THE STRAIGHT RAZOR CURE, one of the most
heralded fantasy debuts of recent times.

Once he was a hero of the Great War, and then a member of the dreaded Black House. Now he is the criminal linchpin of Low Town.
His name is Warden.
He thought he had left the war behind him, but a summons from up above brings the past sharply, uncomfortably, back into focus. General Montgomery's daughter is missing somewhere in Low Town, searching for clues about her brother's murder. The general wants her found, before the stinking streets can lay claim to her, too.

TOMORROW, THE KILLING was chosen as one of the best novels of 2012 by Forbidden Planet, Fantasy Faction, The Founding Fields and A Fantastical Librarian.
