Dude you need to up your standards a little. Responding to someone who just read it and added it to their reading list. Without even knowing if they liked it or not is just kinda sad. Pretty solid book btw love the interesting way you explained how the mc got across how phones work. Just up your standards to reviews or at least comment c'mon man.
For me at least it is very hard to review a novel that I really enjoy but the problems are not very clear and are apart of the things I like about it so if you see me not writing five star reviews for novels that I comment on a lot then it's not because I dislike its just that I don't believe I have the ability to say what I want to say the way I want to say it thats why I comment in chapters the problems that I have with novels I really enjoy
