Thou Shall Not Use Comic Sans: 365 Graphic Design Sins and Virtues: A Designer's Almanac of Dos and Don'ts

Thou Shall Not Use Comic Sans: A Designer's Almanac of Dos and Don'ts - Sean Adams Very entertaining and informative. It is more than about typefaces and fonts, but also layout, printing and dealing with customers - from the designer's point of view. Very short paragraphs about each of the 365 rules, not explaining in detail but pointing in the right direction if more information is needed.

I'm not a designer, or a budding designer, but if I were the latter I think this book would be a useful read. It is quite well designed too :)
