I have finished Alhazred by Donal Tyson. See here:http://www.amazon.com/Alhazred-Author-Necronomicon-Donald-Tyson/dp/0738708925/ref=sr_1_1?s=books&ie=UTF8&qid=1297472475&sr=1-1. I found it quite good. It it a pretty thick book and tries to fill gaps in the life of the Mad Arab Alhazred, the "author of Necronomicon", as invented by H.P.Lovercraft. In other words, Alhazred is a key character in the Cthulhu Mythos. The book describes his travels through Arabia. It is open ended and I regret there is no sequel (it was published in 2006). It brings up an interesting issue, though: Arabia is probably the last unexplored region on Earth. It is a group of closed states and societies and you would need permission and bodyquards. Yet there must be a lot of stuff. There were thriving kingdoms in the past, like Saba. Perhaps the ongoing political changes will open the region. I wish I could go on an expedition there. What about Irem, the City of Pillars? Could it be in the Empty Quarter? The desert itself must be preserving artifacts well.
