[Q]: I really like Christine Feehan. This book was very dissapointing. The plot had promise. Nicoletta was a sweet heroine. The prose were good, and the medival Italy setting was an interesting change of pace. However, the plot flows like molasses in January. I managed to get half way through before I through the book down and went back to the 'Dark' series.
[A]: Negative


[Q]: Beware of the size of this book!If you are expecting to receive a regular size art book, you will be extremely disappointed. The book measures 7.5 x 9 inch and is thinner than my pinky finger.However, if you are just interested in the content, there is a lot to look at and to read.
[A]: Negative


[Q]: I bought this product because I'm living temporarily in a city and will move to another city later, and don't have the extra money to buy a better bed. Since then my shoulders hurt from sleeping on it. I've lost interested in sleeping after that. Before that i never have problems with sleeping.It's ok to sleep for one or two nights only i guess. If you intend to sleep on it for a few months, buy a comfy bed instead of this!
[A]:
Negative
