So I want thrilling plots, yes — but also thrilling language. I want sentences I’ll stop to read twice. This is why standard throwaway airport thrillers don’t migrate well beneath ground. The writing may be “muscular” and “spare,” but if it’s not also “inventive” and “excellent” there’s a good chance the book will wind up abandoned on a platform bench. With a long day behind me and a wearying commute ahead of me, I don’t want to settle for distraction; I want to look forward to reading my book with the palpitating excitement of a second date with someone I’ve already fallen for. I want to miss my stop. Ideally, I’ll miss a few.
