[Q]: It was interesting to read The Foxes of Harrow again, as a "senior citizen, since I was only in my early teens the first time I read...and enjoyed...the book. It is quite sensual, considering the year it was written. It has held up fine during the years. I probably understood the nuances better as an adult than as a teenager. Frank Yerby was a brilliant writer, and in this book he presents a balanced view of what white slave owners and their slaves faced during that pre-civil war era. I couldn't help comparing it with Gone With the Wind as I read it.
[A]: Positive


[Q]: This one doesn't really fall into the Western category, but it's full of hammering action, informative local California history, and mystic goings-on. Seacoast adventures, early Califronia ranching, great good-guys and really bad bad-guys, and mysterious appearances by silent, unknown characters fill this one to the brim! Best of all, L'Amour introduces in this story, for what I believe was the first time in his writings, the famous "portal to the other side," which really sets this story apart from almost all of his other works. Excellent yarn through and through. You won't forget it for a long time after you first read it!
[A]: Positive


[Q]: This is one of the very best "rockumentaries" ever! I loved the whole thing, especially the interviews....especially the ones with the ultra-talented producer/singer/song writer/pianist John Simon-my friend. You might consider checking out John's own recordings.
