Sophie Mouse wishes she could play in the water at Forget-Me-Not Lake with her friends, but she can't because she's a mouse. Or can she? Find out in this third book of The Adventures of Sophie Mouse.

Sophie Mouse likes being a mouse. So she's excited that she and her classmates are making presentations for school about life as the type of animal they are. Sophie has already made a list of things she can do; run fast, scurry into small places, and more. But while playing at Forget-Me-Not Lake with her friends Hattie Frog and Owen Snake, Sophie realizes one thing she definitely can't do: swim!

Hattie and Owen are having so much fun in the water, and Sophie will never be able to join them. Sophie starts to think that being a mouse isn't so special, after all. When Sophie's friends notice her disappointment, can they figure out a way to get her out on the water?

With easy-to-read language and illustrations on almost every page, the Adventures of Sophie Mouse chapter books are perfect for beginning readers.

Poppy Green can talk to animals! Unfortunately, they never talk back to her. So she started writing in order to imagine what they might say and do when humans aren’t watching. Poppy lives on the edge of the woods in Connecticut, where her backyard is often a playground for all kinds of wildlife: birds, rabbits, squirrels, voles, skunks, deer, and the occasional wild turkey.

I think this is our favorite Sophie Mouse so far. Great summer atmosphere. I love that Sophie tried something she felt nervous to do (learn to swim) but then she actually didn't love it and no one pressured her about that. Instead, her friends found another way for her to feel included in their fun at the lake. No peril here, just a sweet and gentle tale of friendship and fun.

(I suppose, if I'm being nitpicky, an adult should have been present while Sophie's friends were teaching her to swim... but these are also stories in which a mouse and a snake are friends, have an owl for a teacher, and everyone subsists on delicious baked goods so I will let it slide)

Sophie identifies the strengths of others but has a hard time identifying her own. She discovers hers at the end of the book.

Her two friends learn to look to Sophie's interest and find a creative way to include her in the way they were playing.

Why so generous with the Stars regarding a children's book? The answer: There's something simply so incredibly refreshing in reading a really good one!

"Forget-Me-Not Lake" is great because of its innocence. It's great because of its overall message. It's great because it has no hidden agendas other than to be a true children's book!

As a parent we want our children to be protected on all fronts. For them to have a period of time within their lives where they are simply kids. The Sophie Mouse books honor that wish.

"Forget-Me-Not Lake" is awesome in that fun facts are learned by the animals themselves regarding their species. What are things that set them apart? In turn, your kids learn certain animal facts in a seamless and fun way as a by-product of simply enjoying the story. Genius! This book also shows inclusion and how friends are able to come together to help insure no one is left out. Incredibly powerful and good lessons throughout; yet, presented in such a way as to not be overt or preachy. It was all done so right! Well done, Poppy Green, well done.

We all have something that sets us apart within our family lines, within our specific person-hood; we all have something to contribute and give. We all have the ability to be inclusive rather than exclusive. We all can be friends. It's all positive messages here!

I highly recommend this series as a read aloud between parents and their kids or for children, who are readers, to read on their own up to age 8 or 9ish.

This was a cute book about Sophie (the mouse), Hattie (the frog), and Owen (the snake) venturing to Forget Me Not Lake. Sophie can't swim and feels kind of left out, but her friends find a way to include her. The animals all have to do a school presentation about what makes their species special and Sophie struggles to find something, but in the end all the animals recognize the cool things that make them unique.

Read aloud with the younger three, again in one sitting. They love this series and I do too. I love that there is mild peril, real emotions, and real conversations and resolutions. The characters are so sweet and fun, a really well done personification of animals while still retaining their individual traits.

My 8-year-old read this to me over several nights when I was sick and had lost my voice. This is sweet story about Sophie realizing that she is a special being, and mice are unique. It’s so easy to compare ourselves to others and forget that we do have unique gifts. The message in this book doesn’t hit you over the head like a Berenstain Bears book and I appreciated that.

Our friend Sophie is back - this time doubting herself and comparing herself to others.

It’s been almost a year since we last read a book from The Adventures of Sophie Mouse series. I think I’ve been trying to push it a little too hard and she’s “rebelled” by choosing something else. But after we finished our last book, Nellie’s Promise by Valerie Trip, I finally convinced her to look through the books she had and she picked this, Forget-Me-Not Lake the third in the series based on the pictures.

Turns out, I was right and she loved the series still! We read through it quickly over 3 separate nights. (Although she would have been more than willing to read it in one sitting!)

As for the story itself Sophie and her little brother Winston are working on a school project about what makes mice unique. But she’s not sure mice are as cool as her friends Hattie the frog and Owen the snake who can actually swim. Sophie does some research at the library to try to discover if being a mouse is actually cool and is surprised at what she finds.

Overall an adorable books and I’m just hopeful she’ll want to read the next in the series sooner than a year from now!

4.5/5

My 6yo: 5 stars! Only I wish I could give it 150 😊
I was a little sad that she couldn't find facts about herself. It's just a good story and the friends are being good and kind. It's good to be helpful to your friends. I loved the facts and I learned new things!

My 10yo: 5 stars
I liked how I was able to learn some facts about animals. I didn't realize that a mouse's whiskers could sense a change in temperature.

Mom: 5 stars
Such a sweet story about appreciating each other's differences and helping each other. Sophie and her friends are sweet and kind, and even when there's small misunderstandings, they work through them gently. Just a lovely series! I also appreciate that even though the books are primarily about Sophie and her friends, all of Sophie's interactions with her younger brother are kind and patient.

Another darling little book! After finishing the first book in the series today, my 3 year old begged to read another Sophie Mouse book. She LOVES these! Our library didn't have the second book available so we read this one (the 3rd in the series) and it doesn't feel like we missed out on anything. From what I can tell, it seems like it is not completely necessary to read these chronologically because based on the two we have read, the plots are entirely separate. My daughter even begged to read another one today but it was bedtime. It looks like we have found a new favorite series! These are a hit! We are both looking forward to continuing the rest of the series.

Even though we don't currently have the target audience, I decided to go ahead and check this out as I recently saw it recommended.
What I liked: Wholesome, sweet, siblings actually seemed to like each other, dad sees daughter in distress and tries at least attempts to fix it, and the mom is a baker.
Cons: Slightly boring. No real danger.
Overall thoughts: I think this would a be a good first chapter book for a beginner reader which is why I'm saving this so that I can remember to give it to my second daughter when she is looking for an early chapter book.

Sophie and her friends go to the lake, but mice can't swim and Sophie discovers that she really doesn't want to learn. At the same time, she and her brother Winston are assigned a school project - each species is going to tell the class what makes their species unique and special. Can Sophie figure out what makes mice special when everything her friends do seems so much more interesting and exciting? A sweet first chapter book about learning about yourself and others, with black and white illustrations by Jennifer A. Bell.

This third book was cute. Hopefully the second book, which had some issues, was just an anomaly. I’d love to have found a series to read with my 6yo. A few other series we’ve tried lately all had the stereotypical “mean girl(s)” in it. Can’t children’s authors come up with more imaginative ways to create conflict? 🙄 Hoping the next Sophie Mouse books will be on par with books 1 and 3!

This is my favorite Sophie Mouse book so far. I’m reading the series with my 7 year old daughter. It’s a great vocabulary builder but defiantly not too challenging. Lovely illustrations. Sophie’s friendships in this book are so kind and supportive. As soon as we finished my daughter asked if we can start the next Sophie Mouse book!

I don't know what it was about this story, but I did not like it as much as the first 2 books. I liked it, but it was not the best yet. It's okay because it was above a 4 star rating anyway. I recommend this series to everyone who might wanna read it. I listen to the audiobooks so might be better or worse to do so. It's up to you to decide how you will consume this one.

My 6 year old loved curling up next to me to hear about the adventures of Sophie Mouse. The story got her attention and we read the whole book in one sitting. We will definitely be reading more about Sophie Mouse!

A sweet little story of Sophie Mouse & her adventures. This is a new series the girls and I started, and I'm impressed with the writing and language, which allows lots of room for questions and side conversations.

Love Sophie Mouse

Love this series with my 6 year old daughter. She is almost where she could read them herself, slowly, with her reading but for now I read them to her and actually I enjoy them also. They are sweet and cute and fun books.

This was the perfect read-aloud chapter book for my short attention span 4 yo. The story was engaging and the characters were intriguing. We are excited to read more Sophie Mouse books and already have several checked out from our library!

Another great addition to the series. Sophie does spend some time feeling down on herself for not being able to do something special. She works it out in the end that she does have something special to offer though, it just looks different from her friends.

Sophie is a mouse who lives with her mouse family and is friends with Hattie the frog and Owen the snake. I was pleasantly surprised at how good this was. My daughter sometimes picks series because they are girly but not very good, but this one was good!

Both of my kids rated this 4 stars. They expressed that they were glad that they learned more facts about the animals in the story. The example they gave was that birds have hollow bones and frogs can breathe through their skin.

These are cute little chapter reads for my kindergartener and usually have a little lesson. This one is about feeling left out of the group and finding your own special skills!
