Julie Morgenstern's books on organizing your space and your life have been a success at Holt, and she is moving for her next to the newly revamped Touchstone Fireside division at Simon & Schuster, where she is its first major nonfiction acquisition. Senior editor Doris Cooper brought her aboard for North American and serial, buying from Joni Evans at William Morris. It was a two-book deal, the first of which will be Managing Your Work Life from the Inside Out, set for fall 2004.
