Friend's bookclub has been working through The Locked Tomb trilogy which has been fun (both to read and to watch other people encounter).

Outside of that, I've been slowly working my way through The Knot Book (about mathematical topology, not kinky stuff), a book about "The Shambhala guide to Sufism", and "Inside Scientology".

I've been going through library books trying to find something at least somewhat straightforward about the modern Sufis and their beliefs/texts/rituals, but all the books I've encountered so far seem to be way more concerned with the historical lens of "Westerners through the centuries trying to grapple with the concept of Sufism and disagreeing with each other about what it is".
