Sunrise Alley by Catherine Asaro is a book about artificial intelligence and androids that develop self awareness. What defines who is human? The main character, Samantha, is an AI researcher who becomes involved in a cross country chase with a man most people think is an AI.
It’s not as good as Catherine Asaro’s other series, the Saga of the Skolian Empire series. The Skolian Empire books are a romantic space opera with lots of good science and great character development. They weren’t published in order (she wrote different books at different times) so I created a list of them in storyline order. The first one is Skyfall (Saga of the Skolian Empire) if you want to get going!
