Ada Sibelius is homeschooled and raised by David, Her brilliant and socially inept single father, who directs a computer science lab in 1980's era Boston. When his mind begins to falter, she is taken in by one of David's colleagues. She is now on a mission to uncover her father's secrets: a process that takes her from childhood to adulthood. This story is highly emotional and I learned quite a bit about Alzeimers. The ending was great but one you will have to read for yourself. If you like books like this one, then you will love this book. Looking forward to my next Liz Moore book. Highly recommend!
