I think it is a good book and has a great moral storyline. If you like books about talking animals read this book. Their are a few hard words so i wouldn't recommend it to little kids.

This was a very good book I couldn't put it down I would really recomend this book.

This used to be my favorite books-the only reason it isn't anymore is that it's a little younger than my age group now. I love Mrs. Frisby and the rats. I think the most interesting part is Nicodemus' story, but the rest is good too. Don't watch the movie (Secrets of NIMH, or something like that)-it's very different, and pretty stupid. I was excited to learn that there really is a NIMH, especially because I think psychology is fascinating.

I read this book after reading The Giver. I think it talks about utopias. The rats try to create a perfect environment where they do not have to steal. I like this book because the characters were interesting and it made me think.

This novel is both exciting and realistic, while imparting positive moral values - the power of friendship, helping others, and improving one's life by hard work, not through stealing.

i just finished reading this book a couple of days ago and i must say it was one of the most boring books i have ever read!!!! At first i thought it was going to be an ok type book but it was the exact opposite! HORRIBLE, CHILDISH, AND BORING are three big words that describe this book.
