Heroes of 9/11 is by Allan Zullo. Another in the Ten True Tales collection, this book contains stories of rescuers and heroes from New York, Washington, and Flight 93. Even though this book was written for young adults, it is well worth the read for adults as well, especially those of us who remember 9/11 so clearly even today. Be prepared to shed a few tears.
