While some say Stapledon's style is dry (it's always been fashionable to accuse sci fi writers of a geeky inability to depict humans and moods), i find it very easy to read and you can zip through Odd John quickly and effortlessly.
The full title - "Odd John: A Story Between Jest and Earnest" implies that Stapledon may have felt much of the story carries an irony. Each reader must let this mysterious work perform its alchemy on them and make their own mind up.
I can't tell of course; that would be unsporting. Prepare to say that your sense of what is moral may receive a long-overdue examination upon completion of this absolutely fascinating book about how a superior being would cope with early 20th century mores, technology, politics, and social convention. You will never forget the book, or John's answer to his plight.
