In the sun-scorched hills of 1920s Los Angeles, oil heiress Aline Barnsdall commissions the enigmatic architect Frank Lloyd Wright to build her dream home—Hollyhock House—a monument as stubborn and unconventional as its creators. As the walls rise, so do tempers, secrets, and an unspoken attraction neither can name. Decades later, restoration architect Marisol Vega discovers letters sealed within the hollyhock-etched concrete, revealing a buried tragedy that shaped the house's haunted silhouette. Alternating between two eras, this novel weaves art, ambition, and longing into a portrait of a home that refused to be tamed—by its builder, its owner, or time itself.
