 Yeah, I mean, basically Cassandra's me. It's quite awkward how much of it is me because I knew that if I was going to do a portrayal of a autistic person, the only real experience I have of that is my own. And it felt quite close to the bone a lot of the times I was writing. So we're in first person in the book because we're really in Cassandra's head the entire time, seeing the world as she sees it.
