Super readable and written with a style and fluidity that makes it easy to understand why so many people have liked it. It's entertaining and I wanted to know where it was going, but the treatment of the characters and themes ultimately felt overly simple.
It felt YA-adjacent, which isn't a criticism on its own terms, but didn't cohere with the apparent ambitions of Tomorrow to say something meaningful about 'adult' relationships over a lifecourse at least up to middle ageish.
