Sandwich: A Novel by Catherine Newman is an instant New York Times bestseller — a moving, hilarious story of a family summer vacation full of secrets, lunch, and learning to let go. Published by HarperCollins on June 18, 2024, the hardcover edition runs 240 pages.

The story follows Rocky, a woman who has spent two decades cherishing her family's yearly escape to Cape Cod. Caught firmly in the "sandwich generation" — pressed between her half-grown children and her fully aging parents — Rocky arrives at their beloved beach rental for another week of sunny days, great meals, and messes of every kind. Her body is changing and her life is too, complicated by hormonal bouts of rage and melancholy as menopause arrives uninvited. When a chain of events sends Rocky into the past, reliving the tenderness and sorrow of long-ago summers, she must face her family's history and future — and the secrets she can no longer keep from the people she loves.

Praised by Ann Patchett as "joy in book form" and by Elin Hilderbrand as "just perfect," Sandwich is a warm, funny, and deeply felt portrait of midlife, family, and the precious weight of ordinary days. Catherine Newman is also the author of We All Want Impossible Things, Wreck, and the memoirs Waiting for Birdy and Catastrophic Happiness. Her books have been translated into a dozen languages.
