The Unseen WorldAudiobook CD - 2016
A heartbreaking and moving story about a daughter's quest to discover the truth about her father's hidden past. Ada Sibelius is raised by David, a single father and head of a computer science lab in Boston. Homeschooled, she accompanies her loving father--brilliant, eccentric, socially inept--to work every day. By twelve, she is a painfully shy prodigy. At the same time that the lab begins to gain acclaim, David's mind begins to falter and his mysterious past comes into question. When her father moves into a nursing home, Ada is taken in by one of David's colleagues. She embarks on a mission to uncover her father's secrets: a process that carries her from childhood to adulthood. Eventually, Ada pioneers a type of software that enables her to make contact with her past and to reconcile the man she thought she knew with the truth.
