I found this book enchanting. Two brothers, given to a monastery in Mongolia at a young age, are separated when one accepts the Buddhist discipline and grows into a monk while the other rebels and thumbs his nose at everything monastic. Separated physically, they're still so close mentally that they know each other's thoughts ... and each wants the other out of his head. Reluctantly they agree to work together on a quest to identify a child who is the reincarnation of a great spiritual leader. You travel with them across magnificent vistas and geographies, puzzling out their complex relationship to each other ... to their responsibilities ... to faith (or defiant non-faith). It's very well written -- the prose is serene and almost dreamlike -- and full of surprises. Do give it a try.
