My favorite is the Iron Fey Series. I love the romance, action and the fantasy in it. It is the kind of book that I love to read! If I have to choose one book of the Iron Fey series, it is hard but I think I would have to choose The Iron Knight. Why? It is mainly because I love that it is written in Ash perspective. Ash is a mystery to me and through this book, I get to see a glimpse of his life and what he thinks. Also, I finally learned to appreciate him and what he did just to be with Meghan! How romantic is that? :D
