London, England (CNN) -- Natascha Kampusch, the Austrian woman who was held prisoner for eight years in a basement, has revealed new details of her ordeal in an autobiography.
In the book, entitled "3,096 Days," Kampusch, who was abducted aged 10 in 1998 while walking to school, describes the relationship she fostered with her abductor Wolfgang Priklopil in order to ensure her survival and the bizarre routines she endured at his hands.
The serialization in the UK's Daily Mail newspaper details how Kampusch was locked inside a "hermetically sealed" concrete jail, beaten up to 200 times a week until she heard her own spine "snap" and was manacled to Priklopil while they slept together in his bed.
Kampusch escaped in August 2006 aged 18 and now lives in Vienna, Austria. Priklopil, 44, an engineer, committed suicide shortly after her escape.
Penguin, the British publishers of the English version, released a statement on behalf of Kampusch: "I now feel strong enough to tell the full story of my abduction for the first time".
