Why isn't life better designed so it warns you when terrible things are about to happen?

I think all families have these secrets, and it's sometimes the strangest things that bring them out. That was part of my interest in the heatwave, in heat as a catalyst for uncovering truths. I was reading Alice in Wonderland to one of my kids recently, and I remembered that it starts on a really hot day. Alice falls asleep because of the heat; the whole story is predicated on falling into a heat-fueled dream.

I think it's dangerous to have lots of time on your hands as a writer. Time to pursue every little alleyway, to follow every single whim. I feel I've done my best writing when I'm stretched for time, when you're most pressured.

You learn so much with each book, but it's what you teach yourself by writing your own books and by reading good books written by other people - that's the key. You don't want to worry too much about other people's responses to your work, not during the writing and not after. You just need to read and write, and keep going.
