While those are in production, I proffer Howard Andrew Jones on ibn Munqidh and on fantastic Arabian literature (going beyond the Arabian Nights! Who knew?!) Jones's Dabir and Asim work (The Desert of Souls and The Waters of Eternity) are really well-done, and strong influences on Legacy of the Bieth. I will unashamedly admit that I have stolen at least one plothook & setup from Jones somewhere.
(Also holy crap, The Desert of Souls is on sale for $10. All y'all should totally pick that up.)
