At first, I thought the book was boring, but after I got halfway thru, it picked up and started to be a very good read. I'm still not sure of all the characters yet, which kept me interested in what happened next. Overall, good book. Some editing needed, so my rating dropped by one star. Hopefully the 2nd book will be more captivating. I've already bought it. :)
Good Review
