Marjorie’s 2016 book, Mamaleh Knows Best, separates the stereotype of the Jewish mother from the historical reality. It looks to Jewish culture and tradition as a guide for bringing up self-sufficient, ethical, and accomplished children. The New York Times really liked it, and Publishers Weekly gave it a starred review. 

Marjorie is also the co-author of Hungry (Simon & Schuster, 2009) written with the model Crystal Renn; the co-author of Smart Sex (MTV Books, 1998), written with Jessica Vitkus; and the author of The Field Guide to North American Males (Henry Holt, 1997), a guide to various boy phyla and their habitats.

She’s a ghostwriter, too.
