'The Magus,' usually described as a book for the young, is about learning that the world is a mysterious and limitless place, beyond our control, and all the more exciting - and daunting - because of it.

Ireland, in breadth, and for wholesomeness and serenity of climate, far surpasses Britain; for the snow scarcely ever lies there above three days: no man makes hay in the summer for winter's provision, or builds stables for his beasts of burden... the island abounds in milk and honey.

The historical novelist has to consider what has actually happened, while the SF writer is dealing in possibilities, but they are both in the business of imagining a world unlike our own and yet connected to it.
