I have been racking my brain. A few years ago I went trekking in Tibet and stayed for a night in the hotel Lhasa. Whilst I was there I met a group of travelers in the lobby and we got talking about a book. Now for the life of me I can't remember what it was called, all I know is that in the book the main character visited the hotel lhasa and he had a guide called Tashi, ring any bells anyone? I know it's vague but please help!
