Narvik, Norway
A remote NATO seismic array in the far north of Norway detects the largest nuclear detonation since the days of the Soviet Union.

Svalbard Archipelago, Norway
The largest icebreaker in the Norwegian Navy, and one of the most high tech vessels operating in the Arctic, disappears without trace.

Arkhangelsk Oblast, Russia
In the chaos following the explosion, the lead scientist on a top secret Russian military research program goes missing with his daughter. There are rumors of sabotage.

The Kremlin, Moscow
A Russian asset, embedded deep within the CIA's London Station, sends a coded message.
"Your missing scientist has made contact. I can lead you right to him."

The Sleeper by Saul Herzog is the stunning fourth instalment in the series that has single-handedly taken the publishing industry, and Hollywood rights departments, by storm. This dazzling tour de force kicks off right where the previous book ended. From the mind of one of the most creative and versatile writers working in America today, this book will surely go down as a classic of the spy thriller genre.

If you listen to only one series this year, this is it. Action, adventure, rebellion, provocative foreign agents, characters you can sink your teeth into. If you're looking for a new spy thriller series that will stay with you long after you turn the last page, look no further.

Recommended for fans of Lee Child's Jack Reacher, Vince Flynn's Mitch Rapp, Robert Ludlum's Jason Bourne, and Brad Thor's Scot Harvath.
