She is an immortal creator of worlds who meets a physicist in a Library Bar. He sees photons cascading from her presence, particles pooling at her feet. For the first time in centuries, she feels complete. But the universe demands more than connection. To anchor existence itself... she must find true love across multiple lifetimes. Each connection bringing her closer to her cosmic purpose and farther from the freedom she craves. For readers who loved The Midnight Library , The Time Traveler's Wife , and The Alchemist .
