Second Deluge [PDF ebook] 

The Second Deluge is a science fiction novel by Garrett P. Serviss, who climbed Matterhorn in order "to get as far away from terrestrial gravity as possible." It tells the story of a devastating flood across the entire earth, and of Cosmo Versal, a modern day Noah who faces public ridicule and disbelief towards his predictions and his Ark project. "Oh, to think that all that beauty, all those great palaces filled with the master-works of art, all those proud architectural piles, all that scene of the most joyous life that the earth contained, is now become the dwelling-place of the terrible fauna of the deep, creatures that never saw the sun; that never felt the transforming force of the evolution which had made the face of the globe so glorious; that never quitted their abysmal homes until this awful flood spread their empire over the whole earth!"
