BPG, depending on your age, whether a book is appropriate for you to read should be between you and your parents or a teacher you respect. Why are you asking your friend? If you ask one friend they will say one thing and another something else. Not all friends read the same books.
There are many things Young Adults ask their friends about that they really shouldn’t. Shidduchim is at the top of the list. Young adults think that their friends know them the best and will give them the best advice. That is rarely the case. The one thing young adults fail to realize is that friends come and go, and the one thing you should never do is to confide too much to any friend. Friends should NEVER know you better than your family. Even though you think your best friend will be your friend for life. Yes that might be the case, but sometimes that doesn’t happen, and they can and sometimes do turn on you and they should never take those secrets with them when they do.
