I looked at several books on 9/11, trying to find one that was approriate for my nephew (age 8) who recently became interested in the subject. I found this book to be the best of lot. It is straightforward and honest without being too scary. Some books dwelled more heavily on the socio-political aspects which lead up to the attacks, and in some cases were a tad on the "preachy" side, or, examined the subject so deeply that a younger child would likely find it boring. Others had a touchy-feely "let's all love one another" tone that somehow de-emphasized the horror of that day. This book tells what happened in clear terms that an young reader can understand, and has several pictures showing details such as the damage to the towers and the Pentagon without being too disturbingly graphic. The child I purchased it for is a third grader, and he was able to read and understand it and, most importantly, I think it helped him to comprehend the significance of an historic event he is too young to remember.
