"1. Who do you like better, Alek or Deryn? (Personally, I think Alek's a complete idiot. No offense.)"
Deryn's more fun to write, because she has a good time at all the things.
"2. Which book in the Leviathan series is your favorite?"
Hmm. Probably Behemoth. I LOVE Istanbul, and I loved going there to research it.
