The main characters of the novel are interesting. The deep dive into their upbringing explained why they deal with life’s challenges the way that they do. Information about how some research is conducted was informative. I would have enjoyed the book more if it wasn’t so very detailed about research, algorithms, etc. It was tedious to listen to. There were times that I actually said enough already! out loud. I am going to finish the audiobook because I’m invested in the couple and Toby and want to see how they made out in life.
