Stephania Astor has survived for more than a century by keeping her secrets buried. Zahara Davis was never supposed to find them. After a photograph from 1916 reveals that Zahara's beautiful, unreadable employer has not aged in over a hundred years, Zahara is drawn into the hidden world beneath Nocturne-a historic Savannah hotel built above a locked threshold known as the Hollow. The door is waking. A rival vampire family wants it opened. And Zahara may be the only person who can close it-or let everything through. Stephania says she is trying to protect Zahara. Zahara is beginning to wonder if protection and possession can look dangerously similar. Ancient vampires. A cursed hotel. A slow-burn sapphic romance. And a door that has been waiting for Zahara all along.
