What's your favorite part about writing books? And do you ever feel pressure when writing a book in case the people your writing it for don't like it?
My favorite part varies—it's the time when you sort of forget you're writing a book because the book seems to write itself. Sometimes this comes during the early drafting phases (and that is magic) and other times it only comes at the very end of revision (that is less magic).
As for the second bit, one of the wonderful things about having a book reach lots of readers is that you have all these readers. But one of the harder things is that now you feel a responsibility toward them. But you also feel a responsibility toward your characters and toward the story you want to tell. Ultimately, I'm writing the books for an audience of one first (that'd be me) and then for you.
