Margolis, a veteran correspondent in the region, presents a detailed overview of the ongoing struggle over the high Himalayas, showing their strategic importance to Pakistan, India and China. Updated throughout for this second edition, including a new chapter on the Taliban. He sorts out confusing religious differences, complex geographies and politics with clarity, explaining -- for example -- the strategic value of the 16,000-foot Siachen Glacier where oxygen-starved Indian and Pakistani soldiers have been fighting for years.  (PKN09, $25.95)
