Q: This book is not for everyone, although most will love the plot. For me, it has too much violence, rape, and other things that just did not seem like a fun idea to me. I think it's better for young adults. Most of my friends who read fantasy enjoy it, so I'm afraid this isn't something I'll continue with until they're older.

A: Good Review

Q: If you're looking for a water softener to reduce mineral build up in your water, this is the product you want. I have used RO systems before, and there isn't a whole lot difference between them.

A: Good Review

Q: A friend of mine has this CD and said "it was so good I had to get it". I heard one song from him the other day, just in time for Christmas - a bit like Neil Diamond on valium. The arrangements are great, the musicianship excellent. It's nice to see them playing with an electric guitar rather than some pedal steel or banjo. Buy it! Even if you're not into bluegrass music, you will still love it. If your friends don't like it, tell 'em what they're missing.

A:
Good Review
