It's like there's this thing you always have guaranteed with this author's writing: whatever the book is about, it'll always have an interesting plot. You can be sure that a) you'll be swept into the plot from moment one and b) lots of unexpected things will happen. Compared to Immortal Rules, this book had a lighter mood. 
 The characters were pretty interesting too, although they were typical. But what came first, the story's characters, or Shakespeare's? According to the book, the more the world remembers you, the longer you live and the stronger you are. So... the faery world in this book is filled with famous faerie characters? Or something? There's no one fairy more older/famous than Oberon? It kind of didn't make sense to me. It's not really something major though - the characters have their unique traits, and the story goes on. 
 To me, Ash and Meghan's relationship happened too fast - at first Ash treats her coldly, then he says he loves her? It felt like Puck was kicked out of the picture - it was near the end of the book, but still -just so they could be together. 
 It was kind of minor, but Meghan seemed inconsistent. Is she naturally understand things, or does it take more than just subtle hints for her? For the lack of better wording, I don't mean it as an insult; some people get the big picture and everything comes together for them in the beginning, and others just go on a roller coaster ride - and again, I don't mean it as offensive. 
 First Meghan goes around making deals with pretty much every fairy in sight - and I personally think giving up your freedom for the rest of your life for your brother is overkill. I mean, people fought wars and ended up losing more than their brothers for freedom. I know she's loyal, but there really isn't anything else? And then that scene that happened at school - it really wasn't obvious for her? Something happens to a jock at school, he blames it on her, the next day, he pretends to be nice - the conversation felt so fake to me; I couldn't help but wonder HOW she didn't get it - she falls for it and becomes humiliated. And then all of a sudden, she tricks a faery by becoming technical on a deal they had made - which was hilarious - but which is she? For me, with the ending, the conversation with the Iron King and Meghan's reaction fell flat, so it ended up cheesy instead of the shivers-down-your-spine type of thing. 
 The bad parts of the book weren't huge, although my review makes it look like it. The plot stood out to me more than anything else; the author writes better plots than a lot of others out there.
