Q: I just returned from a month-long trip to Vietnam and Cambodia, and I found this book extremely useful for Cambodia. Not so much for hotel listings, etc., but for no-nonsense background information on Angkor, Phnomh Penh, and Siem Reap. The Vietnam portion was helpful as well, but I relied more on the Lonely Planet and Rough Guide Vietnam editions for that country. I would definitely recommend this book to someone traveling to Cambodia over the Lonely Planet edition, which is *really* outdated.

A: Positive

Q: I recall this recording on LP in the early fifties. It conveys the humour and genius of Mozart with great singers although other than Steber they were not previously identified with WM.

Q: I read this book for the first time more than 10 years ago, and I found it fascinating. I have read it again from cover to cover at least twice since then. It is very well researched, and I couldn't put it down. I wish I knew where Ms. Auel got all the information she did on the herbs and plants that she describes in her book, that the characters (Iza and Ayla) use for medicine. Some of them (like the willow bark) I know for a fact were used, and I wonder if all of the other herbs and plants really work the way she describes... Guess I'll have to check on herb and plant books for that matter! In any case, I also read the other books of the series (The Valley of Horses, The Mammoth Hunters and Plains of Passage), and I regularly check to see if Ms. Auel has published another book of this series. Hurry Ms. Auel, there are a lot of us waiting to hear what happened to Ayla.
