Daughter of Mine by Megan Miranda

The new thrilling novel from Megan Miranda, the instant New York Times bestselling author of All the Missing Girls, The Last to Vanish, and The Only Survivors.
When Hazel Sharp, daughter of Mirror Lake's longtime local detective, unexpectedly inherits her childhood home, she's warily drawn back to the town-and people-she left behind almost a decade earlier. But Hazel's not the only relic of the past to return: a drought has descended on the region, and as the water level in the lake drops, long-hidden secrets begin to emerge...including evidence that may help finally explain the mystery of her mother's disappearance.
