"I built my empire from nothing, Reckless. Now watch me tear yours down, piece by piece."

Ellie Reckless has carved out her place as London's criminal arbitrator, keeping the peace between warring factions through favours and brutal negotiation. But when a vicious Liverpool crime family launches systematic attacks on legitimate businesses, what starts as a straightforward case explodes into something far deadlier.

Someone with intimate knowledge of London's underworld is feeding intelligence to the attackers - someone who knows exactly which businesses to hit, which people to target, and how to watch Ellie's carefully maintained peace burn to the ground.

As bodies start dropping and the investigation spirals out of control, Ellie discovers she's not just fighting external enemies. Two ghosts from London's bloodiest past have crawled out of Moses Delcourt and Danny Martin, both with scores to settle and their own twisted agendas. Whether they're connected to the attacks or simply feeding off the chaos, their return threatens to ignite a war that will consume everything.

With her team under siege from personal demons and old enemies circling like wolves, Ellie faces her most dangerous challenge yet. Can she outfight forces that have had years to plan their revenge...

or will London's streets run red with the blood of a conflict she can't control?
