|This book is about the quest to the centre of the earth. The expedition is led by Professor Otto Liedenbrock and includes Axel and their Icelandic guide Hans. Liedenbrock stumbles upon this discovery when he was going through a runic script. In the runic script he discovers a coded message written by an Icelandic alchemist Arne Saknussemm, saying that he has been to the centre of the earth. He goes on to describe how exactly he did it. So Professor Otto Liedenbrock, Axel, and Hans go to Sneffels where they are let down by cloudy skies. But on the last day the sun comes out and they enter the correct crater. Once in they face many mishaps like being in a chamber filled with combustible gas and face several prehistoric creatures.
