I read a book as a young teenager in the late 1950s entitled Roommates; it was about two girls who bonded as roommates. The book was touching and so poignant that I realized the potency of literature then. I believe the first name of the author may have been Rosemary. I probably borrowed the book from the Brooklyn Public Library.
The author is Laura Cooper Rendina.

Thank you so much. I am grateful for the author’s name and I just ordered a copy of my childhood book inspiration.
