Crichton and Clancy — do they have sex scenes in their books? We do want something in that genre. Dune is more science fiction, no?
I can read a million reviews on Amazon, but the reviewers are not going to mention scenes that are in there, and I’ve read enough mysteries to know that there can be stupid things about how the detective finds himself “reacting” to the lovely blonde witness, in detail, etc...
Try “Shogun”...the book (audio) is better than the series they ran on TV, great for a long trip and “sensual”, not sexual.
