My wife picked up several fine books about Mongolia in preparation for our travels there.  I have read exactly none of them.  She tells me Mongolia is a lot like Tahiti, but I am not so sure. 

Here's a list of some books I've seen on Amazon about Mongolia, or in some cases, Tibet:

• Mongolia (Lonely Planet)
• Yak Butter Blues
• Here Be Yaks
• Yak Butter & Black Tea
• Mongolia: Nomad Empire of the Eternal Blue Sky
• Modern Mongolia: Reclaiming Genghis Khan & Peter Graves
• Best Yak Butter Blues Clubs of Northern Mongolia (out of print)
• Frank Lloyd Wright & His Impact on Mongolian Architecture

Ok, some of these don't really exist.  

But my wife is a big fan of Frank Lloyd Wright. And if he ever made it to Mongolia, maybe on his way to some fancy hotel design assignment in Tokyo or whatever, and someone got a picture of him with a Yak and wrote a story about it into one of those self-indulgent self-published Samizdats on Amazon, I would certainly buy it for her.  Cuz that's the kind of guy I am.
