The Number of Love by Roseanna M. White is a historical fiction novel that takes place in World War I and focuses on Margot De Wilde, who deciphers intercepted messages for the Allies. But the book is not just about Margot breaking codes; it is also about Margot finding love. I liked the historical setting of the Great War, and the book’s mix of suspense, mystery, and romance. Margot is strong and smart, and the author believably portrays her as a genius. White is a skilled writer who weaves her words beautifully. One of my favorite sections reads as follows: “Margot had never had any particular feelings toward the night. It came, it went, at calculable times. She didn’t fear the darkness, and she didn’t love it.” White’s words flow with a natural flair.
