***Spoiler warning: If you have not read the Iron Fey series yet, do not proceed if you do not want the book ruined for you.
Each one of these characters feels like they're real and a part of you. Puck is also different from before. It seems like in the first two books Puck was the one grinning and smiling and Ash was the one smirking. In this one, they've switched positions. Puck's changed a lot. You see the unemotional, ancient faery part of him more, not the happy, warm human side (Even though he's not human. But he pretended to be one for long enough.)
As for Ash, he's the total opposite. He's so much more open, which makes him even more appealing (as if he wasn't already super hot!). This book is so sad, because of Ash and Meghan's romance. It seems like they're doomed to never end up together, but I really hope it turns out right! I thought it would all end, but I knew Ash would never give up! Kudos to Ice Boy. The ending of this one just left me screaming (still mentally. Don't want parents or neighbors thinking I'm crazy.) I need to know what happens next! If there was no Iron Knight, I would die.
