I love this book and wanted to reread it almost immediately after I first read it, although maybe choosing to read it again as 2020 rolled into 2021 wasn't the wisest idea I've had. If it was one sentence? Humans spoil everything through self-aggrandizement, even when they don't mean to, but lyrical and with time travel. It's a gorgeous book but it is fundamentally sad, so choose your timing carefully.
