I am very fond of extraordinarily handsome rats. <3 Even better than I remembered, and now I have to read the sequel to find out what happened to everybody.

Reread for our monthly classics readalong--discussion on the blog this Friday!

This was one of my all-time favorite books when I was a kid; I must've read it eight times. So I was pleased to find that it holds up well, and I still found it very entertaining (although it seemed a shorter). I did notice some things that I don't think really registered when I was younger. For one, I was thinking as I read that Mrs. Frisby is a pretty unusual character for a children's book. She's an adult, which is not common to children's novels; usually the protagonist is the same age or a ...more

I loved this book so much as a young teen, I read it over and over and over. This is probably the book that started me off on my lifelong love of fantasy, together with Watership Down.

I re-read this as part of my MacHalo Reading Challenge 2016, 4. Re-reading a childhood favourite.

The beginning was a little boring and the very traditional gender roles of the mice annoyed me a bit at first. But once Mrs. Frisby met the rats and they told her their story, the book picked up a lot. I had forgotten

1. Mrs. Frisby and the Rats of NIMH mostly takes its place in Mr.Fitzgibbon farm. Mrs. Frisby who is a widow has 4 children. One day, one of her brightest kid Timothy becomes sick. The plowing was soon starting, but Timothy couldn't move out of his bed. Even after eating the medicine Mr. Ages gave, Timothy had a big chance that pneumonia will recur. That is when Mrs. Frisby started to find ways they could move without getting Timothy sick again. She went to her neigh

This book captivated me from start to finish when I read it - for the first time - as an adult. It's such a beautiful story of courage and morality and heroism. It's hard to imagine anyone not being moved by "The Rats of Nimh" and its characters are well-developed and not easily forgotten. I thought about this book for days afterward, and I was sad when it ended.

There are really two stories going on at once; O'Brien cleverly brings the two together slowly by revealing their connection detail by

This is a book that I had fond memories of from originally reading it in the 4th grade. I was considering buying it as a gift for my niece, who's that age, so I thought that I should read it again myself first. Naturally, I was a bit concerned that my memory of the book would be let down by the passage of time. Thankfully, I was wrong.

This is a great story full of memorable characters and plenty of adventure that keeps the pages turning. Children and adults alike will enjoy this award-winning no

I suggested this book to my stepdaughter. She read a few pages and declared it to be boring. Oof, shot right to the heart. I loved this book when I was kid. LOVED. I reread it to try to figure out if there was something wrong with me, with her, or with this book.

Decision--nothing wrong with any of us. I read the first few pages and realized why this doesn't appeal to her. It's a bit of a slow start and, my apologies to kids these days, I don't think most kids these days have the same level of p

This was always one of my favorite movies as a child, though I still love it now, and I was very excited to read the book. I wasn't disappointed. This book was thoroughly entertaining and extremely amusing. I loved it from the very beginning. Mrs. Frisby and her family were loving, resourceful, and easy to like. I loved reading about the rats and their adventures

The story had a slow beginning for me, but then it really picked up. Although the central theme was on Mrs. Frisby's struggle to relocate her home, there was also this larger backstory on how the rats of NIMH became so intelligent and their connection to Mrs. Frisby's family that I really got caught up in. I was a little disappointed though whenever Mrs. Frisby's story took to the backburner. Mrs. Frisby is such an admirable, brave character. She puts herself in harms way to save her children, j ...more
I think it was my second-grade teacher who read this to us in class, like a chapter a day, or something.
I was so into this book, I made my mom take me to the library where I checked it out so I could read ahead to find out what was coming. But I didn't want the entire thing spoiled, so I only read a chapter ahead.
In fifth grade, this was available through RIF and I remember seeing the copy on the folding table among all the many other free books. I snatched it up so fast, grabbing up from under

A lot like Watership Down but slightly less important and infinitely easier to finish. It's probably been ten years since the last time I read this which is weird to think about. If you live in Springfield, I'm starting a book club and this is the first book we're reading; come to the downtown library tomorrow evening if you wanna be in it. You don't have to have a copy or have started reading it yet.

Will I ever find a talking animal book to equal "Watership Down"? Doubtful. And that's okay.

But in my latest jaunts through the great kid lit of the 20th century, "Mrs. Frisby" is a standout. O'Brien sets up a talking-animal world with what seem at first some loose conventions, and while his young audience may not notice, the genre-savvy reader immediately notices something is up. Mrs. Frisby and her family can read? They can use medicine? Heck, they know what a postcard is? Then O'Bri

Mrs. Frisby and the Rats of Nimh by Robert C. O'Brien

I picked this book up at a yard sale a while back, and it was promptly shelved. Hesitant to read it to my kids, there it sat. The hesitance stemmed from my memories of the rather creepy movie version I used to watch as a kid.

I was wrong to wait. Mrs. Frisby and the Rats of NIMH is a delightful story, full of mystery, adventure, science, and compassion. In short, we loved this Newbery Award winning classic.

Mrs. Frisby may be just a little mouse

I forgot how much I love this book. I was a little nervous re-reading it because I hadn't read it since I was a kid and I was worried that it wouldn't hold up well, but I needn't have worried. The book is just as wonderful now as it was then.

One of the things I find very interesting now is the way that humans are portrayed. Not bad or good, but just very human. Going about their lives not really appreciating how they affect everything around them. But also not entirely clueless.

I was taken aback at how involved I became in the story of Mrs. Frisby and the Rats of NIMH. From page two, I accepted the short brisk writing style of O’Brien and went with these mice on their long and taxing journey. I thought Mrs. Frisby was, at first, a bit too simple of a character but as the story progressed you certainly find more depth. I found the illustrations to be gorgeously drawn and the climax of the novel perfectly executed. With the many childrens books I’ve read, this is definit ...more
Another children's classic I missed...Since RABBIT HILL was one of my favorite books when I was a kid, I fell right into this story of mice and rats who speak and read. Funny how the cat, Dragon doesn't seem as bright.

Mrs. Frisby is dealing with so much...the loss of her beloved husband, Jonathan, the illness of her youngest child, and the upcoming destruction of her cozy winter home by the farmer who will plow up the field where her cinder-block home rests.

She begins a strange, dangerous journe

Great book. I unfortunately watched the movie first which mostly ruined Robert C. O'Brien's story so don't waste your time with the movie. This is a wonderful book that I will one day move from my bookcase to my son's bookcase when he's old enough to read. Easy 5 star.

Just read this book with my four-year-old son. It's hard to know what percentage he understood, but as long as he is still interested and asks me to read another chapter then I keep going and don't worry too much about comprehension since I figure it develops by reading and discussing. He was even more motivated to read it when we picked up the movie (The Secret of NIMH) from the library and I told him we could watch it after we finished reading the book.

Towards the end of the school year, my fourth grade teacher started reading this book to the class after afternoon recess — one chapter each day. Then, just as the plot started to ramp up and get really interesting....the school year ended. We didn't finish the book. And, of course, by the time I got to the public library to check it out, one of my classmates must have beaten me to it.

And then 20 YEARS went by.

That is a really long time to not know how a book ends.

V. Gingerich
Story begins nicely, goes into (fascinating) back story for most of the book, comes back to present and ends spectacularly. Love it in spite of it all. Students love it, too.

I remember the first time I read it, or rather, my teacher read it to me. He said, "You'll never, ever look at rats the same way again."

Susie Finkbeiner
My kids enjoyed this one. It's slow moving, so if kids are used to flashy, quick stories, they might be surprised by this one. Most of it is backstory and I would have loved for the NIMH part to be a different book because it really could have been fleshed out more. However, this was written at a time when this was common for kids books.

In 5th grade a boy gave me this book for valentines (he didn't give anyone else a book, and I had never talked to him before, didn't even know his name!) and I ADORED this book until I lost it 15 years later. I always kept it either near me or in my car to read whenever I had time to kill, no matter how many times I've read it. I am very sorry that I lost it, and will have to purchase it again (though the sentimentality can't be replaced).

This YA story of sentient animals is a gem! Mrs. Frisby, a field mouse, lives with her four children on the prosperous farm of Mr. Fitzgibbon. During the winter, the family lives in a cinderblock in a field. Just before the Fitzgibbons plow the field in preparation for spring planting, the mouse family moves to their summer home on a stream bank. A crisis arises the Frisbys’ cozy, predictable lives when Timothy, the youngest son, contracts pneumonia. Even though Mr. Ages, a white mouse doctor, p
