I was hoping to have a story focused on Garak and investigating what happened to Nan Bacco with the True way.
That is pretty much the story! Which does make the cover somewhat misleading. I hope the cross cult cover will be better. Picard and company do have a role to play, but its Garak's book.
I don't even think they are on the enterprise for more than a couple of pages. The rest of it is Cardassia.
