Unseen World by Liz Moore

Unseen World by Liz Moore

Ada Sibelius is raised in a computer science lab in the 1980s by her brilliant but eccentric father, David. He is a pioneer in artificial intelligence, working on a program called ELIXIR that aims to mimic human conversation. When David begins to succumb to early-onset Alzheimer’s, Ada's sheltered world collapses. As she grows up, she realizes that her father’s past is a complete cipher—even his identity may be a fabrication. Using her own skills in coding and the very digital legacy her father left behind, Ada embarks on a decades-long quest to decrypt the truth of who David Sibelius really was.

Why You’ll Love This Book

Moore constructs a labyrinth where the walls are made of computer code and failing memories. The narrative treats David’s Alzheimer’s as a tragic decryption error, where Ada must use the AI tools her father built to uncover the man he was before his mind began to delete itself. It’s a haunting look at identity in the digital age, suggesting that even if a person’s biological memory fades, their "unseen world"—the work, the data, and the legacy they leave behind—might be the only way to finally see them clearly.
