There was a lot i liked about this book,  the presentation of how reddit/Twitter works and blows things out of proportion was very on the nose and I enjoyed it! 
What i didn't like was that one of the main characters was an incel? I'm guessing so the author could present a "both sides" argument,  but it fell flat to me,  because I just.... don't think there's any excuse for men that think like that.  It's immature,  selfish and cruel.  I found it was unnecessary and ruined a lot of the enjoyment of the book.  I love Jason Pargin but this isn't his best.
