banshee.reviews shared a tip "Despite being dull and very British, this was an interesting book. Less plot-driven than I expected from the summary; you get very into the MC's head, and his growth as a person is just as important as what actually happens in the book. I wish there was an actual resolution, though. By the end of the book, nothing really changes in the big picture, which is fairly disappointing."

rowan_mccrindle shared a tip "read this for my English class, and it might be the first book I've read for school that I've truly enjoyed! it's so quotable and I like the pacing and hinting that James uses. i don't like Theo as a main character, and the whole ending leaves something to be desired for me - I don't like the religious emphasis - but the simple idea of humanity unexplainably becoming unfertile is such an interesting concept, the faults of the book do not matter so much. also, it's pretty different from the movie!"
