What was supposed to be a simple exchange in Paris turns into an ambush. Danny Pearson walks into a hotel room to find two assassins waiting for him, a hire van with a crate and chains parked outside, and a dead man who was never who he claimed to be. Someone didn't just want Danny dead - they wanted him taken alive.

Before Danny can find out who set him up, he's snatched off a London street by a fake police unit, drugged, and shipped to Russia in a cargo crate. He wakes in Lefortovo Prison, Moscow - one of the most brutal jails on earth - with the Volkov mafia waiting for him on the inside.

Annika Volkov is her father's daughter. Young, ruthless, and ice-cold, she has spent five years rebuilding the criminal empire Danny destroyed in Book 1. Now she's bought a prison governor, corrupted Moscow's police, and blackmailed a British cabinet minister into delivering the one man she holds responsible for her family's destruction. Her orders are clear: Danny must suffer endlessly, but he must not die.

With no weapons, no allies, and no way to contact the outside world, Danny must survive daily attacks from Volkov enforcers while forging an unlikely alliance with Leonid Turgenev - a rival crime boss imprisoned by Annika for the same reason. Together, they plan an escape that will take them through the most dangerous corridors in Russia.

Meanwhile, in London, MI6 spymaster Howard is closing in on the traitor who sold Danny out, uncovering a web of blackmail, corruption, and murder that reaches into the highest levels of the British government.

Blood Runs Deep is the sixth instalment in the internationally bestselling Danny Pearson series. A relentless, high-stakes thriller that brings the Volkov saga full circle with savage action, a chilling new villain, and a conspiracy that spans London, Paris, and Moscow.

Perfect for fans of Andy McNab, Chris Ryan, Mark Dawson, and Lee Child.
