The final book in the 2025 reading-discussion series is The Secret Life of Sunflowers by Marta Molnar, a gripping and inspiring novel based on the true story of Johanna Bonger, Vincent van Gogh's sister-in-law. It begins when Hollywood auctioneer Emsley Wilson finds her famous grandmother's diary while cleaning out her New York brownstone; the pages are full of surprises, but the greatest surprise is that the diary isn’t her grandmother’s, after all, but was written by Johanna as a 28-year-old widow with nothing to her name—except some paintings. . . .
