This was recommended to me by Goodreads. I was highly anticipating it because it sounded extremely interesting. Now, I have to say that I was thoroughly satisfied with it and it was quite an enjoyable read, but I had a couple issues with it. Not too much, but a little. 
 The plot was basic, in my opinion. It was the standard beat-the-villain kind of thing. This is what bothered me. I wish the plot was more complex and different from other books. It would have made this book even more enjoyable. 
 Something that frustrated me was that I couldn't tell who the lead was. Was it Stephanie, or was it Skulduggery? The book is told in Stephanie's perspective, but she doesn't seem to be doing much in the fights and sometimes I was just yelling at her to do something. On the other hand, the entire book was named after Skulduggery, and he does seem to be featured quite a bit (view spoiler)[(he destroyed the Book AND defeated Serpine, the main villain) (hide spoiler)] so honestly, I couldn't quite tell. It frustrated me because I couldn't decide who to focus on. 
 I was also a bit annoyed that we didn't get enough development out of other characters, such as Ghastly and Tanith. I really liked both of them, but I guess that was why the book is part of a series. 
 Stephanie and Skulduggery were great characters. I loved the humor laced into this and I absolutely adored it. The magic system is well thought out, too. Some things didn't stick with me, but that's alright. I'm looking forward to reading Playing with Fire as soon as absolutely possible.
