Blanche Lake is not like the other mothers who come to collect their children at the local nursery school on New York’s Upper East Side. She lives alone, has a job, and has never been married. It’s the first day of school when this story begins, and Blanche is eager to see how her daughter, Bunny, has fared away from home. But her expectant waiting becomes a mother’s most dreaded nightmare: Bunny never materializes. Neither teachers nor students recall the small girl, and soon Blanche is engaged in a frantic search for any trace of her missing daughter. And the worst part is . . . no one believes her.
