Books that are heartbreaking, but yet full of hope and inspiration

So an author friend of mine, (I feel I can call her a friend, we've chatted often enough now) gave me this link (she happens to be an author of one of those books) and it lists books that are about being a teenager and the struggles one has.  I really thought this was brilliant and loved how the writer of the article pointed out the different depths of the books.  I haven't read them all yet, but the ones I have read are certainly books that will stick with me.  I wanted to share the link with all of you since it's so great and is a great list of recommended reading if your looking for something in particular.  So go here and check it out! 

I'm also hoping maybe some of you would be up for donating some of these books, or any others in new to gently used condition, to the Pine Ridge Reservation book drive.  You can find the info about it here.   I think all of these books would be fantastic as the struggles that the teens go through on the reservation are more frequent.  More alcoholism, more drug use, more suicides.  Sometimes a book can make a world of difference. 
Even if your not able to donate you really must get your hands on these books and read them!
After posting the above bit I got some great comments with MORE inspirational books!  So I thought I would add them to the list here.    Karen says Split by  Swati Avasthi should be on the list.  I recognize the cover but really don't recall reading any reviews on it.   I'm definitely going to be watching for it though!

 Angel says Tell Me a Secret by Holly Cupala should be on the list.  I have heard good things about this one! 
She also says A Blue So Dark by Holly Schindler.  It's another one I've heard many great things about.  Both of these books are ones I can't wait to get my hands on!
Do you have some that should be added to the list?
