Flipped through this at the bookstore. An exploration of graph theory and its applications--it looked interesting.

Although it's a very casual approach to this branch of mathematics, it is a book filled with puzzles and explorations that should be accompanied by a scratch pad and a pencil: you will frequently want to pause and explore some of the puzzles on your own.

I thought the book would have been improved by additional figures throughout the text. Occasionally the author's text explanations took a little too much effort to figure out.

A quote from the further reading section, referring to 2 of the author's sources: "Both of these books are weighty tomes in the modern American style." I am grateful to have discovered this slim volume in what is presumably the English style.

(I am the only person to have checked this book out from the Penn library in its 5 years on their shelves. Poor neglected book!)
