Kolymsky Heights, Lionel Davidson, 1994, USA first edition, very good condition of book and dust cover.
A coded message is smuggled out of Russia, a plea for help from a supersecret laboratory deep in the frozen wastes of Siberia. The note is addressed to Johnny Porter, a Canadian Indian of the Gitxsan tribe with a genius for languages and disguises, and reluctantly he is forced to slip across the border on a rescue mission, the consequences of which he little imagines. The detailed picture of life in the Kolyma region and of the native peoples of the Russian Far East (such as the Evenks) and British Columbia (such as the Tsimshian) is impressive.
A Siberian permafrost hell lost in endless night, 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.
