In 1884, Edwin A. Abbott combined mathematics and philosophy in the classic tale Flatland, in which he made fun of Victorian England's stiff society while introducing the concept of life in four dimensions. In 2001, Ian Stewart (professor of mathematics at the University of Warwick in England) has gone a push beyond in Flatterland, an updated modern account of two-dimensional characters confronted with the unbelievable: multi-dimensions!
 
Victoria Line (yes, that's a pun at the expense of London's Underground), great-great-granddaughter of Abbott's original narrator A. Square, has stumbled upon his diary in the attic. Her father, in a hysterical rage, has destroyed the diary because of its obvious heresy. What he does not know is that Vikki has saved a copy on her computer, enabling her to contact the Space Hopper. She joins the Space Hopper as his student, journeying through the Mathiverse in the "virtual unreality engine." They encounter characters such as The Hawk King, Schrödinger's Cat, The Charming Construction Entity, The Mandelblot, and Moobius the one-sided cow (and you thought Alice in Wonderland's characters seemed a bit odd!). If you enjoy the complexities of modern mathematical theory and can take a healthy dose of pun, you will love this sequel to Flatland.
