Having written a book on PLO leader Yasir Arafat, the Wallachs have now turned to the "emerging generation" of Palestinian leaders. They have concentrated mostly on Palestinians from the West Bank and Gaza who have been closely associated with the peace negotiations with Israel. They succeed in presenting 12 Palestinians with distinctive life histories. Only one is a supporter of the Islamist Hamas movement. For some reason, they completely ignore the new generation of leaders from outside the occupied territories. But despite these limits, the book fills a gap by putting a human face on a people that is much in the headlines but little known by most Americans.
