** spoiler alert ** 
 Nevernever thought I would find another amazing unborring story after Hunger Games. (though I still think Hunger Games is my first favorite YA fantasy story XD). I love every part of this book and may be more than the previous books. Gladly adding one more star if I could. 
 Every characters grows quite natural, though Meghan changed a bit too quick. Bulied girl to queen in.. Hmm.. Let's say a few months? Yeah, may be it's not that strange. Well, she's daughter of The Summer King. Still, she's remind me of typical fantasy hero (SLAP! XD) 
 I like Ash here. He wasn't a perfect prince charming for he has emotion and humour side. 
 Love The Iron Queen Robin Goodfellow. Guess I've finally found The Puck I've lost in The Iron Daughter. He's more likely himself. Same goes with Grimalkin. 
 For other characters, even they had a short appearance, I could catch their true nature. Like Mab who still loved her son even though she had banished him. Love the cute Razor too XD 
 So much love scene in this book. Too much. Fortunately not sickening. 
 There's one scene forced by Kagawa for the sake of story. Yep. It's when Meghan asked Ash to be her knight. (hmm... I can smell fan service in the air ;) ) but still okay for me. 
 The plot was great. No wasted scene. Love the basic idea merging summer and iron magic. Almost no finding of plot hole. But I'm just wondering. What happened with Ash's vowed to kill Puck? :P 
 Aaanndd... The Ending! I love Kagawa's choice of ending! XD Not happily EVER after, but not happily NEVER after either. A twist ending. I'm glad that there would be a sequel performing my favorite duo -Ash and Puck- plus.. (maybe) the-annoying-smart-mouthed-but-cute cat, Grimalkin. ;)
