Kolymsky Heights - Lionel Davidson

'The best thriller I've ever read, and I've read plenty. A solidly researched and bone-chilling adventure in a savage setting, with a superb hero.' Philip Pullman
Kolymsky Heights. A Siberian permafrost hell lost in endless nights, the perfect setting for an underground Russian research station. It's a place so secret it doesn't officially exist; once there, the scientists are forbidden to leave. But one scientist is desperate to get a message to the outside world. So desperate, he sends a plea across the wildness to the West in order to summon the one man alive capable of achieving the impossible ...
Fast-moving, exhilarating and starring a highly unusual hero, Kolymsky Heights is an unforgettable thriller with a spectacular denouement.
