The year is 2035, and Los Angeles County is awash in a tangelo haze of wildfire smoke. Xandria Anastasia Brown spends her days deep in the archives of the Huntington Library as the curator of African American Ephemera and associate curator of American Historical Manuscripts, supported by an array of AI personal assistants and health bots.

Although Xandria's work may preserve collective memory, she is losing a grasp on her own. Evren, her new health bot, won't stop reminding her that her symptoms of long COVID are worsening; not to mention that severe asthma, chronic fatigue, grief, and worrying lapses in reality keep disrupting progress on a new Octavia E. Butler exhibition, cataloging the new Diwata Collection, and organizing the Huntington against a stealth corporate takeover. Then, one morning a colleague Xandria can't place calls to wish her a happy birthday—and the library goes into an emergency lockdown.

Sequestered in the archive with only her adaptive technology and flickering intuition, Xandria fears that her life's work is in danger—the Diwata Collection, a radical blueprint for humanity's survival. Up against a faceless enemy and unsure of who her human or AI allies truly are, she must make a choice.
