A Goodreads user asked:
what maturity level do you think someone must have to read this book? i am 15 and i don't really joke around about this subject, I'm just scared the ending or the way the characters handle the situation might freak me out.
Sofia I am thirteen, I read it. I am pretty mature for my age, a lot. But, it is a tough book, it talks about controversial and thoughtful topics that are not easy to handle. If you are not mature, it can freak you out.
