In the 1970s in rural North Carolina, in the shadow of Brown Mountain and its mysterious fabled Lights, fifteen-year-old Quinno Moore and his older sister, Gabrielle, are recent orphans, a situation made worse by Quinno's illness. To pay for his healthcare, Gabrielle implores Quinno to make a deal with a doctor to take his reclusive son on a hike up Brown Mountain. Joined by his best friend Kenny, Quinno and the doctor's son venture up Brown and discover a little boy, muddy and alone, in the middle of the forest. Unbeknownst to Quinno, a young woman on the other side of Brown Mountain, Judith Wright, lives in an estate and poses daily for an ominous sculptor known to her only as The Mason. The Mason intends to carve her exact image into a pillar of marble to display on his estate. Judith's memory is not trustworthy and with a lurking sense of unease, she pursues botanic wildcrafting, an interest instilled by her mother, and begins to see and hear strange things in The Mason's gardens. After his gardener disappears, Judith concludes that there have been more people roaming around The Mason's estate than she originally assumed. Who these people are, however, she is uncertain. As the mystery unravels and their stories collide, Quinno and Judith must reckon with harrowing truths about their pasts and take back control of their lives.
