This was absolutely harrowing. The details of what Brandon and Richard had to do just to get out of the building were vivid without being too graphic, and made me feel like I was right there. The same is true of Reshmina's struggles to try to keep her family safe when her twin brother is determined to join the Taliban and her village is under attack. There is a lot of information about what life was like for Reshmina, which was quite interesting, and the politics of the situation were well balanced. Notes at the back are helpful for young readers who won't have as much familiarity with the topic. This is probably the best book about 9/11 that I've read. It's a perfect accompaniment to Arash and Reedy's Enduring Freedom.
There are a number of nonfiction books about 9/11; I know because I purchased many of them for my school library in 2002! I expect that there will be a number of books coming out this year. It's fairly easy to find fiction books on this topic, and several such as The Big Apple Diaries and a graphic novel version of Tarshis' I Survived the Attacks of 9/11 are coming out in 2021. There are not a lot of books about Operation Enduring Freedom (Spradlin's biography, Ryan Pitts : Afghanistan, Patterson's Operation Oleander, McKay's Thunder over Kandahar, Reedy's Words in the Dust and Massey's Torn are the only ones that come to mind), so it's good to see some coverage of this as well.
