Eight months since losing her mother in the Spanish flu outbreak of 1919, twenty-one-year-old Lillian Carter's life has completely fallen apart. For the past six years, under the moniker Angelica, Lillian was one of the most sought-after artists' models in New York City, with statues based on her figure gracing landmarks from the Plaza Hotel to the Brooklyn Bridge. But with her mother gone, a grieving Lillian is rudderless and desperate - the work has dried up and a looming scandal has left her entirely without a safe haven. So when she stumbles upon an employment opportunity at the Frick mansion - a building that, ironically, bears her own visage - Lillian jumps at the chance. But the longer she works as a private secretary to the imperious and demanding Helen Frick, the daughter and heiress of industrialist and art patron Henry Clay Frick, the more deeply her life gets intertwined with that of the family - pulling her into a tangled web of romantic trysts, stolen jewels, and family.
