I love Chasing the Mountain of Light: Across India on the Trail of the Koh-i-noor Diamond
. Mystery and adventure and intrigue all rolled into one. I do read non-fiction, but I generally don't devour it the way I do fiction... however, this true story had me entranced. Sadly, I don't think it's available as an eBook in ANY format... I checked BooksOnBoard, Amazon, etc... I can only find the dead tree version. But it's definitely worth reading.
