This is not an ending. I just want to say this straight out at the beginning of this review. While this book does bring an end to a trilogy, there's still lots of story left to tell & Kagawa is going to be continuing it in the next book in the series, The Iron Knight. I honestly can't wait for that one because this one (Iron Queen) was so awesome. 
 Words cannot say how cool this book was. Harlequin seems to have a great nose for talent & Kagawa is no exception. Lots of things happen in this battle- we finally get the huge drag out battle between the seasonal & iron fey. We get to see more of Meghan's non-bio father. There's more development in the Ash/Meghan relationship. And of course, there's more Grimalkin- my favorite character in the series. (Note to Kagawa if she somehow finds this review- I want a spin off novel or series following him around!) 
 I'll give you fair warning that this ending will be both surprising & not surprising to you. I expected a lot of what happened at the end, but some of the stuff took me by surprise. I actually liked how it ended but I know that there will be some who won't, so hopefully me posting this non-spoiler spoiler alert will prepare some people for the ending of this book. An ending that was sort of bittersweet. (Now I know I'm being way too spoilery!) 
 If you've read the previous two books then you have to read this one. I'll warn you though, it'll only make you that much keener to read the next book in the series!
