Iain Banks (known as Iain M Banks when he’s writing science fiction) had the most extraordinarily fertile imagination. It was one of the reasons his books have been so loved and respected. His last SF book before he died of cancer in June at only 59 was The Hydrogen Sonata, in his Culture series. I’d not read any of his books before but was very struck by the way people talked about him over the summer, and so decided to make amends. Well, I certainly dived into the deep end.
