The book was divided into several sections, most or all narrated in first person and each about one of the Biblical matriarchs: Sarah, Rebecca, Rachel, Leah, etc. Along the lines of “The Red Tent” but young adult and published somewhere around 1980, give or take a couple of years. The author was female, and I think it was published in US (though possibly UK or other British Commonwealth, since I got it out of a Canadian library).
Stump the Bookseller
New format, same book stumper solving.
To clarify: I think it was more likely an American publisher, but it could have been a British one.
Possibly this one?
“Sarah and after : five women who founded a nation” by Lynne Reid Banks (1975) Relates the lives of four generations of girls who became the matriarchs of the Hebrew nation. Has chapters on Sarah, Hagar, Rebecca, the sisters Leah and Rachel and Dinah
Possibly Madeleine L’Engle’s “Certain Women”?
