After Winna's little sister breaks her glasses, her grandfather gives her an old-timey pair of spectacles that belonged to her great-aunt Estelle. The specs are silver and perfectly circular, with tiny stars on the bridge and earpieces that curl all the way around her ears. Best of all, they're magic. Because when Winna makes a wish beginning with the words "What if"—that is, when she speculates—the spectacles grant it. Winna wishes she could see ghosts … and soon she meets not only the real Estelle, but Estelle's mother, Winona. Nearly a century before, Winona escaped from slavery and ran north with her baby, Key. But Key was stolen from her under mysterious circumstances, and now Estelle and Winona have a mission for Winna: Find Key. He's still alive. He doesn't know the whole truth. And unless Winna can solve the mystery and bring him home, a powerful curse called the Burden will smother out their family's lives—and Winna's mom could be its next victim. This beautifully written historical fantasy by an award-winning science fiction author offers new twists and turns in every chapter and will leave you looking at your own family's roots with new eyes.
