Flatland: A Romance of Many Dimensions

Flatland by Edwin Abbott

2 great sf books http://en.wikipedia.org/wiki/Flatland Set as a satire of Victorian society "The story describes a two-dimensional world occupied by geometric figures, whereof women are simple line-segments, while men are polygons with various numbers of sides. The narrator is a square named A Square, a member of the caste of gentlemen and professionals, who guides the readers through some of the implications of life in two dimensions." http://en.wikipedia.org/wiki/The_Black_Cloud I won't spoil this one for you, it's just a really interesting and suspenseful sf story. Richard Dawkins (writing in the 2010 Penguin Classics reissue) claimed the novel was "one of the greatest science fiction novels ever written."
