The Iron Fey
Truthfully, this is one of the best books that I have ever read, and could possibly be one of my favorites. The storyline and premise were brilliant and hooked me within the first few pages. I have read other Julie Kagawa books in the past which were just as amazing. Yes, there was swearing, but it only added to the comedy throughout this book. And I have to admit that the main character was quite cowardly at first, but there are (around) seven books in the series and the main character definitely improves in the next books, (certainly not mean or selfish or stupid). The hidden morals are inspiring and the supporting characters, in my opinion, are in no way bad at all.
I adore this book and I am currently reading the fourth one in the series, Iron Knight, which I am loving thoroughly. I would definitely recommend this book, or any of the authors' books, to anyone who shares my taste in adventure fantasies.
