Random House is supporting the March release of A to Z Mysteries: The Missing Mummy by Ron Roy with an event kit and national sweepstakes. The kit includes bookmarks, disappearing-ink pens, and reproducible games and activities. Grand prize in the sweepstakes—the Alphabet Zweepstakes, as it is being called—will be lunch with the author plus a Super-Sleuth camera. Entry details can be found at the back of the book and on the company's Web site, www.randomhouse.com/kids.
