I tried to read this book when it first came out. I couldn'tfinish it. There seem to be at least three themes or storylines in here struggling to get out. One seems to be a reasonably good alternative-history novel based on the idea that the pirate subculture of the 1700s might have formed a revolutionary constitutional regime. Unfortunately, this quickly becomes mixed up with maundering about certain ancient "cities of the red night" and a very great deal of homosexual imagery and fantasy. As the book goes on (as far as I read it, anyway) the main storyline becomes increasingly lost. I ultimately found it both distasteful and so muddled as to not be worth it.

Ex Output:
Negative

I was impressed with speed of delivery, condition of product & quality of packaging for the product.The soundtrack itself is wonderful as I saw the original movie when it came out and feel Madonna & Antonio deserved a better review than they got for their performances.

Ex Output:
Positive

Ex Input:
This is by far his worst effort that I've read. He's not my favorite spy author,anyway. This book feels like it had been written to fulfill a publisher's contract or obligation that Mr. Higgins had assumed and needed to finish in a hurry. The characters are not at all fleshed out, and the story line is too contrived. I would advise not wasting time by reading this book.

Ex Output:
Negative
