i really enjoyed it, and i also quite like the ending. like all of Qntm’s works it is written in a quite “confusing” way. Details are omitted for you to figure out and the story is not told in chronological order. although the prime example of cronology being used in Qntm’s work is the book Fine Structure.
I like that particular style of storytelling, and the authors work in general. So i can recommend it, but then again that is also just personal preference.
