On a number of occasions, it had been suggested that I read this book, and I must say I'm very glad I did. I got very involved, as the writing was so wonderfully descriptive. Having said this, I don't think it was arduous to read all that detail, which sometimes makes reading a book feel a bit of a chore. I would recommend it to anyone!

Ex Output:
Positive


Ex Input:
This is a great book so far. I am a little farther than halfway into it and it is great. Although the writing is a little choppy at times, it is definitely worth it.

Ex Output:
Positive

Fantastic book! I was kept on the edge of my seat from beginning to end! This book is definitely going to be the start of an excellent series. The novel is based back in Venice, just around the decline of the Byzantium era. My favorite characters were without a doubt Manfred and Erik.This book is an excellent buy!

Positive
