Two debuts this week: John Ringo's Hell's Faire (Baen) on 2 hardcover lists, and William C. Dietz's Halo: The Flood (Del Rey) on 2 paperback lists.
Gibson's Pattern Recognition has dropped off all lists. Jordan's Crossroads of Twilight remains on one list, New York Times'. Laurell K. Hamilton's Cerulean Sins is still going strong after 4 weeks (not counting pre-publication sales at Amazon).
Wall Street Journal's list has been updated on the CNN site for the first time in many weeks; it may be dropped anyway from this chart to make room for something else, perhaps lists from Canada and Australia.
