Well, this book was interesting. I should seriously stop judging books solely by covers and buying them because it's pretty.
The characters were possibly the only saving grace. They were pretty well-rounded and well-thought through characters, with the exception of maybe one or two minor characters.
The writing style was pretty bland, it reminded me at times of someone telling you a story in a pub. Often the grammar was off and the paragraph structure was abismal. I'm not even sure if it was even necessary for the story to be set in the 17th Century, those characters could have fallen into any century and adapted well - though the archtectural employment of the protagonist fits in well.
Not much else to say, the plot wasn't exactly guessable but it wasn't specifically enticing, either. All in all, a bit of a disappointment.
