This just in from Publishers Weekly:
The last time J.K. Rowling did a U.S. book tour, many of the people who are now her biggest fans either weren't born or hadn't learned to read yet. But to promote Harry Potter and the Deathly Hallows, the notoriously publicity-shy author will be coming to the U.S. in October for the J K Rowling Open Book Tour. The brief tour, her first in eight years, will include four events: two in New York, one in New Orleans and another in Los Angeles. Three of the events will be expressly for students while the final one, slated for Carnegie Hall in New York, will be open to 1,000 fans who win tickets through a sweepstakes sponsored by Scholastic.
