She was thrilled to death with how crowded the bookstore was (very), and extremely pleased to do Q&A (she seemed to really enjoy the questions, and finding answers to them).
She also sounds just like you'd imagine from her writing. Alright, just like I'd imagined, anyways.
She was extremely flattered by the little anecdote I offered her of her being the only author who ever made me get lost on public transit- she laughed very loudly, and was pleased as heck to be thanked for a chance to return a little of the enjoyment she'd given me.
Very wonderful author. If you get a chance to see her read, I strongly recommend it. Best author reading and signing I've seen, bar none.
