I've been a longtime fan of Mercedes and own most of her Valdemar series. So, of course, I picked this book up at my local store. After wrestling through 50 pages, I gave up! I plan to sell it back to my local store ASAP- this is nothing better than a paperweight in my bookshelves. The worst part is, my boyfriend picked it up and tried reading it. Now he thinks that this is a good example of her work!
Negative

I guess I didn't find this CD memorable, as I couldn't even remember what it sounded like. There were no particular pieces that jumped out at me and cried "Dance to me." Overall I was not that impressed.
Negative

Never ordered it, it was sent by mistake and I returned it upon receipt without even opening it so I don't know.

Negative
