The Complete Idiot's Guide to Feng Shui Book

Origins, form, and compass schools. Qi, Yin-Yang, the five phases, the eight trigrams, your house, and the environment surrounding it. The eight house system, personal trigram formula, good and bad directions, people compatibility. The flying stars analysis.
Perhaps the most complete book around feng shui I've found. Very complete of technical aspects, practical advice, but easy to understand, not too difficult. There aren't so many books on this genre, and I think the majority may underestimate or deviate from the original teachings. It is a tradition that has to be respected and maintained, not modified for improvisation or oversimplification.
