This book is very engaging and definitely worth reading. Some people might initially dismiss some of the core plot ideas as old and overdone (a young orphan boy, raised by his aunt and uncle, exceptional only because unlike everyone else he has no 'magical' abilities is living in a small isolated village, on the outer edges of the realm)however, Jim Butcher manages to completely suck you into the world he has created (more original than many other fantasy worlds) using a form of magic that is original and very satisfying to read about.
This book works best if you consider it the first instalment of a larger story, Jim Butcher has very carefully started some (initially seemingly unimportant) plot lines that develop beautifully as the series continues.
As with the reviewer before, I stumbled upon this book (and series) because of Jim Butcher's Dresden Files, which I also enjoyed a lot.
And although the Dresden Files series are unquestionably the better known series (no wonder as it was started earlier and has been adapted into a T.V show), I have to say that it's this series that really makes him stand out as an author for me.
I'm completely and utterly addicted to this series, I read the first and second books in one sitting, stopping only for lunch and supper, and then read the third book the day after.
Please read these books - they seem painfully unappreciated, especially considering how good they are!
