I enjoy this book very much. It is a timely classic with which I am happy to now have my own copy.
Positive

The sizing of this costume was fairly accurate but it very cheaply made. After only a few wears, the mask and belt both broke. I wouldn't recommend this costume.
Negative

Christine Feehan does it again, for all of you that have only read this one book by her, i strongly suggest that you read them all!
