Flatland: A Romance of Many Dimensions by Edwin A. Abbott, 4/5

This bizarre little story is told from the perspective of a two-dimensional “Flatland” dweller, whose visits to one-dimensional “Lineland” and three-dimensional “Spaceland” encourage the reader to consider how very plausible it is that there exist in reality unlimited additional dimensions, of which humankind is arrogantly ignorant.

Why I read it: my dad lent it to me and I had heard of it before (I can’t remember where).
