Emotionally scarred after witnessing the bloody climax of the Beslan school siege in Russia's North Caucasus, in which 314 hostages died, Tom Parfitt set out on a journey. In High Caucasus, he shares his remarkable thousand-mile quest in search of personal peace - and a greater understanding of the roots of violence in a region whose fate has tragic parallels with the Ukraine of today. Starting in Sochi on the Black Sea and walking the mountains to Derbent, the ancient fortress city on the Caspian, Parfitt traverses the political, religious and ethnic fault-lines of seven Russian republics, including Chechnya and Dagestan. Through bear-haunted forests, across high altitude pastures and over the shoulders of Elbrus, Europe's highest mountain, he finds companionship and respite in the homes of proud, little-known peoples.

Rising in the Mongolian mountains and flowing through Siberia to the Pacific, the Amur River forms the tense border between Russia and China. This is the most densely fortified frontier on Earth. Harassed by injury and by arrest from the local police, Thubron makes his way along both the Russian and Chinese shores. By the time he reaches the river's desolate end, a whole, pivotal world has come alive.

Sylvain Tesson found a radical solution to his need for freedom, one as ancient as the experiences of the hermits of old Russia: he decided to lock himself alone in a cabin in the middle taiga, on the shores of Baikal, for six months. Noting carefully his impressions of the silence, Sylvain Tesson shares with us an extraordinary experience.
