I'm not a huge fan of novels that take liberties with established folklore, and I love the traditional view of the Fay as heartless, cruel, and unable to touch iron, but it didn't bother me here because this is urban Fantasy, and you can't have characters who have to stay far away from iron without dumb complications (it's just not possible in cities)--as also because, come on, this shit's not real.The cover cracks me up because what I love about McKenzie, our first-person narrator, is that she is strong, but it's in a very traditionally feminine way--she's a human with very specific cartography skills, and while all the female faeries are badass fighters, McKenzie's strengths are her brilliance, her stubbornness, and her capacity to love and forgive. I don't care how cheesy that sounds, I love this character, and I'm glad she refuses to fight with a sword. There has to be something she can't do.I like urban fantasy with strong female protagonists, so this was kind of a perfect book for me. If either of those things are not your cup of tea--if you're too silly to be able to suspend your disbelief and read fantasy--then this is not the book for you.
