It was cute. I wouldn't read it again. I felt that Adam was an empty character, and the reader doesn't know much about him at the end. Example: what food does he like? Olive very clearly likes sweet food, and it is explicitly included in the story. Adam likes... vegetables? Healthy food? Olive only makes jokes about it, it is not explicitly stated. I want to feel a connection to both characters, and to do that I need to know more about them. We get to know a tiny bit of Adam's childhood (and mostly through Holden) and his academic history. That's about it. He doesn't have much dialogue. Forgettable fluff
