Can't disagree there. Lol. The Disappearance of Haruhi Suzumiya was absolutely fantastic.
I'm currently reading through Mirall's Mansion as I type this. I can't help but agree that Cecelia is best girl. Carmine and Mirall are both great, well-written characters, but CC, her actions and her backstory... it's all just so endearing! I hope that she's present in more stories!
