The Unseen World

Moore's third and perhaps most ambitious novel (after Heft and The Words of Every Song) is large in scope, as it explores the philosophical issues surrounding human vs. computer consciousness, but it is also a small-scale, powerfully local story about a young girl. The details of Ada Sibelius's day-to-day life in Boston's Dorchester neighborhood, homeschooled by her genius father, carry this narrative. She is forced to grow up fast, helping her father and his team at a computer science lab, and caring for him as he suffers from early-onset Alzheimer's. As his health and memory rapidly decline, she discovers her parent was not who he said he was, and with the help of a private investigator and a local librarian, learns more about him and his sacrifices than he would ever share with her. The story also flashes forward to the present and near future, when Ada is working for a tech company to produce a virtual reality world.
