Where did you get the idea for your most recent book?
I wrote an article about climate change for a science blog. The ensuing discussion was...depressing (to put it mildly). It wasn't fun to talk with old people about how they do not want to change anything in their lives. So I stopped talking with the old guys and began writing a post apocalyptic SciFi for young adults, in which a 15 year old girl tells us about her world (that we screwed up for her)
