The Newbery Honor–winning author of Wolf Hollow and Beyond the Bright Sea returns with the story of an unforgettable young heroine in Depression-era Maine. After the financial crash, Ellie and her family have lost nearly everything—including their home in town. Forced to start over, Ellie has found a welcome freedom, and a love of the natural world, in her new life on Echo Mountain. But there is little joy, even for Ellie, as her family struggles with the aftermath of an accident that left her father in a coma. An accident for which Ellie has accepted the unearned weight of blame. Determined to help her father, Ellie will make her way to the top of the mountain in search of the healing secrets of a woman known only as "the hag." But the hag, and the mountain, still have many untold stories left to reveal and, with them, a fresh chance at happiness. Critically acclaimed author Lauren Wolk weaves a stunning tale of resilience, persistence, and friendship across three generations of strong women, set against the rough and ragged beauty of the mountain they all call home.
