That ending though!
I loved this book. You do have to be aware it’s written in 1989, but even so it’s great! There’s fantastic rep in this, diverse, human characters of both sexes, different classes, ages etc. Sexuality isn’t there though. He makes physics less obscure than it is and extrapolates his future brilliantly from what he saw around him. His writing itself was intriguing and well done. I loved all his references and descriptions and relationships. Also, it’s a sort of multi format, like a toned down illuminae. Absolute must read for science fiction fans.
