The book We All Looked Up is from the point of view of what would happen if the world was ending very soon. There is no certainty that the world will end but they also can't be sure that it won't. I really enjoyed this aspect of the book, the uncertainty that there is throughout the whole story. I thought the choices the characters made were realistic and that it was all very well thought out and written. I loved how the book made me think about what I would do if I only had a certain amount of time left to live and what I would want to be doing with this time.
