Congrats to Hyperion senior editor (and former PW Book News editor) Maureen O'Brien, whose acquisition, A Monk Swimming, debuts this week on our nonfiction list. Author Malachy McCourt, brother of Angela's Ashes author Frank McCourt, is in the midst of a month-long tour to 15 cities -- where he not only gives readings at bookstores but leads his audiences in rousing choruses of "Molly Malone!" This rousing chronicle of Malachy's immigration to New York City nearly 50 years ago has 163,000 copies in print after four printings.
