Sloane, a real estate agent with a unique gift, is still reeling from the spectral love and devastating loss of Julian. But her grief can't silence the new "echo"—a profound melancholy humming from a sleek, mid-century modern home. There, she discovers the silent, mournful ghost of Eleanor Vance , a brilliant 1950s architect trapped by unacknowledged genius and a dark secret. Eleanor's only communication comes through flickering lights and moving objects, but Sloane soon uncovers a chilling truth: Eleanor's revolutionary "family room" design was stolen by a jealous colleague, Arthur Sterling , who then murdered her to cover his tracks. Now, with Caleb , her steadfast contractor, unknowingly threatening to destroy the hidden evidence, and a greedy relative, Marcus Thorne , pushing to sell the house to a developer, Sloane must race against time. Driven by her own heartache for Julian and a fierce determination to right a century-old wrong, Sloane must piece together Eleanor's story, expose Arthur Sterling's crime, and reclaim Eleanor's legacy before it's erased forever. But bringing peace to a lost soul comes with a personal cost, pushing Sloane to the limits of her new abilities and forcing her to confront her own lingering grief. Some echoes refuse to be silenced, and some hearts deserve to be heard.
