When foreign governments act like gangsters, a new kind of SAS is needed . . .In London, assassins carry out a deadly chemical weapons attack at the royal wedding. All the signs point to a Kremlin-sanctioned hit. Their victim: a notorious mobster. 'The Cell' is a shadowy unit within the SAS, dedicated to fighting global organised crime. In a world where the Russian government is the real mob, it's the job of the Cell to defend British interests at home and abroad. Only the elite are selected, only the very best will survive. For SAS staff sergeant Josh Bowman, whose young family was brutally murdered by an Albanian crime gang, it's a chance for revenge - and to bury his secret opioid addiction. But the Russians have only just begun. When the Cell uncovers a sinister plot against a British-backed tyrant in Africa, they are quickly drawn into a deadly race against time. Soon they find themselves fighting a terrifying enemy in a brutal fight to the death. Outnumbered, outgunned and with no military support, Bowman and his comrades are all that stand between Moscow and ultimate victory . . .
