Out of these books, can I get help which is the most sad one to read for my next read?

So I actually don't know if this is the right sub for this

But so I have got, by many suggestions of tearjerking books:

Hamnet by Maggie o ferrel

Extremely loud and incredibly close by Jonathan safron foer

Bastard out of Carolina

Anyone tell which is the most most sad?

The most sad book for me was the book thief in the past.

Thanks for the help!
