Publisher's Synopsis
Fourteen days ago, CIA headquarters in Langley, Virginia, received a cryptic message from an agent operating deep undercover in Russia: 'He has betrayed us and wants to go to war.' Unable to make contact, the Director of Operations is forced to turn to one of his most deadly field officers - Will Cochrane. His mission is simple: infiltrate the remote submarine base in eastern Russia's Avacha Bay, locate the MI6 agent operating under the code name 'Svelte', and decode his message - or die trying. It's a near-impossible task, even for a man who carries the code name 'Spartan'. Meanwhile, political and economic tensions between the U.S. and Russia are rising by the day... It's up to Will to discover the identity of the legendary operative known only as 'Sentinel'.
