This quick read was funny, quirky, and made me wonder if ghosts were real. There is some simple geometry involved, but figuring out the descriptions made by the narrator, A. Square, with the help of geometrical diagrams made this novella all the more enjoyable for me. I'd recommend this book for people who: like reading about different dimensions, are ok with math, & like laughing at the chauvinistic eccentricities of a government ruled by geometric shapes.
