Unseen World by Liz Moore

Raised in the quiet hum of a 1980s computer science lab, a gifted young programmer must use the artificial intelligence software her father created to decrypt the secret history he took to his grave.

Ada Sibelius grows up in the unconventional sanctuary of a Boston technology lab, home-schooled by her brilliant, eccentric father, David—a pioneer developing ELIXIR, a revolutionary AI program designed to mimic human conversation. But Ada’s sheltered world shatters when David succumbs to early-onset Alzheimer’s, leaving her isolated and confronting the realization that her father's past is a complete cipher. As David's memory unravels, Ada uncovers subtle clues suggesting even his name and identity were elaborate fabrications. Armed with her own programming talent and the digital fragments embedded within ELIXIR, Ada embarks on a decades-long search through historical archives and lines of code to uncover the truth of who her father really was. A deeply moving story of dark family secrets books and emotional resilience, Liz Moore’s Unseen World explores the intersection of artificial intelligence, grief, and the hidden legacies that outlast human memory.
