I found this little tale so compelling, I burned through the book in a day. Twelve-year-old Matthew Gore, an ordinary British schoolboy, comes up with what seems to be an imaginary friend; a little late in childhood, his parents think, but his sister Polly had had Piff some years before, so they thought they knew how to handle it. But Matthew’s friend Chocky becomes increasingly disruptive and begins to seem less like a friend than a dybbuk. Is Matthew possessed? Does he have a guardian angel? What is the nature of their relationship, and what does Chocky want? Wyndham had a deft way of recreating childhood *and* parenthood, in ways that made me think about the purpose of education and exploration, even what makes us human. A simple story that opens a lot of questions.
