If you're open to reading young adult books (assuming you haven't already them), I strongly recommend Nnedi Okorafor's Nsibidi Scripts books. The first in the series is Akata Witch. It's a favorite that I return to from time to time.

Um. . . No, thanks.

I don't know whether I've ever encountered bakhour. Does have one signature fragrance? Or is it like incense, where there can be many scents?
