Coming on April 7 from Workman Press.

It’s been nearly 15 years since Alvarez’s last novel for adults, and she returns with the story of Antonia, a retired professor whose life is upended by the death of her husband and the appearance of a pregnant undocumented teenager at her door. Alvarez, the author of “In the Time of Butterflies,” “How the García Girls Lost Their Accents” and more, explores the changing notions of family and what we owe each other.
