Speaking of Ash, I know he has some serious emotional baggage, but I find him hard to like for much of the book. I'm pretty sure repeatedly telling a girl you will kill her if necessary isn't good boyfriend material. That said, he is an interesting character with all his flaws and issues. Seeing how much he cared for his first true love humanized him somewhat. Still, I hope his feelings for her are resolved in the next book or in the fourth one, The Iron Knight. Who wants to have the hero of the story still pining for his dead ex?
The story line follows Meghan through her attempts to prevent the Iron fey from destroying all of the Nevernever and stopping the war they have engineered between the Winter and Summer courts. I never really cared for the quest aspect of the story. I know this sounds awful, but the faeries as a whole have been terrible to Meghan, and the Winter court in particular is brutal toward humans. Even the Summer court is, at best, callously indifferent to the world outside faerie. (I mean, Oberon just wanders around having kids with mortal women and never caring much about them, and that's just one example.) I kept wondering why Meghan cared so much about the fate of the faery realms.
Although the plot and romance left me a little cold, I have to give Julie Kagawa credit for writing the most elaborately described, intricate scene details I've read in a long, long time. When she's telling what a room looks like, don't skim. It's worth your time to see what creative things she'll come up with next.
