In 6th grade, my teacher read us the same book mentioned in the Tumblr post. It's called "We all fall down", and it's written by Eric Walters and is a fictional account. At the time, the book had only come out a couple years prior. It's a good book. It's well informed, well written, and it never talked about who was to blame, only the tragedy that occured. The author is also Canadian and he wrote a sequel that covers the aftermath and emotional trauma for survivors and their family members. It's not a book about the attack, it's a book about loss, grief and shock, and about how people can come together to heal from it.

Of course, it sure doesn't sound like this teacher was trying to send that message. I just wanted to shout out a good book.
