question:
Great Gift Great Value - I had to get one for myself. The glasses are over sized and the shaker stirs up a great batch of dry Martini's. I love the retro glass look and the shaker has a seal to prevent leaking while shaking your favorite drink.
answer:
Positive


question:
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!
answer:
Negative


question:
The plot and characters are incredible. Everyone that likes the supernatural should read this book, and all the other Night World books. I think I'm in love with Ash!
answer:

Positive
