> books .. communicate something

> convince or to inform. It's literally the pretext for all communication

ok, so what does a dirty novel, or some other pulp fiction convince or inform you of?

Sex is communication too. It speaks to whatever escapism you desire or taboo you want to happen before your eyes.

You can call the popular "taken off my feet by the mysterious handsome Werewolf that will fight to the death for me" trite. But readers into that have a pretty clear message they want to receive.
