Anticipating Mrs. Frisby

I had never read Mrs. Frisby and the Rats of NIMH and to be honest was not really looking forward to another book with talking animals.  The plot was very different than what I expected in my preconceived notions mostly just based off of the title.  I read a book review that focused on "social sensitivity" in this book.  It stated that O'brien presents the effects of science as profound but neither all bad nor all good.  I thought this was interesting because this is very unique to fantasies and many present technology as evil.  The same review quotes O'brien saying that "The mind learns that it is not easy to separate good from bad; they become deviously intertwined. From books [one] learns that not all doors are simply open or shut, and that even rats can become heroes."
