I think the mistake I made with "That Eye, the Sky" is not to have more humour in it, because the book had a lot of humour. But, unfortunately, with the novel being written in the first person, a lot of the humour comes from the little boy interpreting the events and the situations he finds himself in and that he observes. So we are party to his sense of humour via his inner thoughts. When you pull that away, you have to come up with an orthodox third person approach. I really wish we had come up with more humour.
