The mix you mention really catches my attention: a neurosurgeon, witchcraft and that gothic atmosphere of New Orleans... it sounds like a super powerful combination. Of course, I have a little respect for what you say about it being a dense read that requires patience, but if the setting is as good as you make it out to be, it's surely worth the effort. I'm writing it down for when I feel like something deeper and more immersive. Thanks for the information!
