I know nothing of One Direction, except the things I have learnt on tumblr. But I have been informed that this is fiction with play by play borrowed scenes from Louis life.
Either you write fanfiction and make no profit, or you come up with your own stuff. This is someone's real life no matter if you change a few small things. It just doesn't sit right with me.
I did try to give it a chance, but I could not get into it. It was just not a good book from where I am sitting.
