I need a good book

I've been wondering, how much a book can change a person's perspective on life and things. For example, a book that's changed me definitely was The Remarkable Journey of Coyote Sunrise. 

 But we're not here for that, what are some good book recommendations for a girl in middle school or any book recommendations in general. 

I would like to have the books be about deeper topics like, getting over addiction, su1cide, or dealing with loss

If you have a good book that might not meet the criteria it's ok! You can still recommend it!

Keep in mind, though I will be borrowing the books from a school so noting related to sex.
