Some treasures are too precious—and too perilous—to keep. Evelyn Chan has been the backbone of the Silver Springs Public Library's book sales for four decades: a pillar of honesty and community service. But when she discovers a rare poetry collection worth hundreds in a donation box...everything changes. It should be worth celebrating, but the book isn't just valuable…it's personal. Inscribed 'To my darling Martha', it connects to her dear friend Martha Henderson's long-ago confession about a forbidden romance. With the library desperately needing funds, Evelyn faces an impossible choice. Keep the secret safe? Or let the book go to auction? Evelyn needs to think, so she slips the volume into her bag. But as mysterious text messages, flustered conversations, and half-remembered stories pile up...has she stumbled onto Martha's deepest secret? And should she...keep it hidden? Sometimes the most precious discoveries aren't the ones we're looking for—and sometimes the most poignant secrets are the ones we stumble upon.
