A New York Times bestseller!

Part of the Shapes Trilogy, the books that inspired Shape Island from Apple TV+

The beguiling second entry in the innovative shape trilogy by multi-award-winning, New York Times best-selling duo Mac Barnett and Jon Klassen.


This book is about Square. Square spends every day taking blocks from a pile below the ground to a pile above the ground. This book is also about Square’s friend Circle. Circle thinks Square is an artistic genius. But is he really? With the second story in a trilogy of tales about Triangle, Square, and Circle, Mac Barnett and Jon Klassen nudge readers toward a more well-rounded way of looking at things. Understated and striking in its simplicity, this funny, thoughtful offering from two of today’s most talented picture-book creators emphasizes the importance of keeping your eyes — and your mind — open to wonder where others see only rubble and rocks.

The second in a basic shapes picture book trilogy by Mac Barnett and Jon Klaasen--the first was Triangle, which I also like a lot--that is part of their efforts to deepen the picture book form. As I have said repeatedly (maybe about Klassen in particular, whose Hat trilogy I love) the works of these guys are almost unique in picture book creation in that they refuse to speak down to small children. They expect to engage them, through simple shapes and plenty of (literal) space for reflection, in some deeper questions about art, aesthetics, and relationships.

Square has a job, taking squares out of a cave (what, Plato?!) into the light, and Circle (can we begin to imagine book #3?!) sees the squares and mistakes Square for an artist (and a genius) who is creating images of himself. Is he an artist? He's just doing a job, right? But wherein does beauty reside? Can a mundane task in everyday life also be beautiful? And what aspects of artworks or the artistic process--art "work"--are not mundane or "everyday"? Why do we presume Art as the site of "genius" and not, say, digging a hole (another book by these guys)?

Commissioned (or maybe just asked) by Circle to make a "portrait" or refection of her, Square fails--hey, he's not an artist!--and defeated, he falls asleep in the rain. Awakened by Circle in the morning, she sees a work of genius: Her reflection in a pool of rainwater that she assumes he iintended. Conceptual art, she thinks. But we know it is coincidence, made of failure. Her perception as "critic" makes the work "genius." But what place does accident or mistakes or chance or serendipity have in the creative process that some critics decide is genius? How much is subjectivity part of the process of assessing an artwork (or any kind of work)?

Yup, all these ideas are in this hyar picture book with simple drawings, and yup, you can engage kids (and even adults, if they are willing!) in these issues through this book!

Book Reviewed by Stacey on www.whisperingstories.com

Last year I reviewed ‘Triangle‘ by Mac Barnett and Illustrated by Jon Klassen. This is their second book in what is going to be a trilogy of books about different shapes.

This book follows Square who lives in a secret cave. Every day he goes to the bottom of his cave, chooses a square of rock and carries it outside of his cave. One day whilst doing this, Circle rolls past. She thinks that Square has made the square rocks to look like himself and wants him to make one just like her. Square isn’t a sculptor though and now he must try and make a circle for his friend, but he doesn’t know how too. What will he do?

I’m a fan of the artwork by Jon Klassen. I understand some people are not keen on the blandness and darkness of his work, but I find it really intriguing and visually pleasing.

The story of Square trying to do something he is not sure how to, just to please his friend is really quite sweet. It is a short book, with only a few words on each page. This makes it a great book for those learning to read.

Square in an interesting book, I can’t wait to see which shape Mac and Jon choose for their next book.

Square is absolutely my favorite of Mac Barnett's unique Triangle, Circle and Square Shapes trilogy.

Square is like many of us, just getting by and not feeling particularly special, but Circle sees greatness in him. Square doesn't trust himself, but Circle does, and even when he feels he's failed, Circle still sees genius.

We all need a little Circle in our lives.

Mac Barnett and Jon Klassen’s Triangle was one of my biggest disappointments last year. BUT it was also the picture book that made the strongest impression, inspired the most discussion, and had me waiting on the edge of my seat for the next book in the series. Soooo….Barnett and Klassen must be doing something right. :)

This is Square’s story.

We meet Square as he’s doing his daily chore of dragging and pushing his square shaped blocks out of his secret cave and up the hill. This is his work. Circle floats on by---She floats!!! Brilliant! Circle sees the blocks as sculptured works of art and calls Square a genius. She wants Square to make something for her now. But Square didn’t make the squares. Can Square become a sculptor to sculpt a perfect circle for Circle?

I loved this book! From the design to the questions it asks. We get Klassen’s trademark simplicity along with his tan and brown coloring with dashes of pale teal on the page. Plus those eyes! Oh, how I love the look in Square’s eyes. How does Klassen do it? One slight shift and the whole look goes from questioning to panic to relief. Then we have the “Oh crumbs!” lines and cute little arms and perfect turn of the page comedic timing. All of that and more add up to storytelling gold!

Square also serves as a fantastic kick starter for discussions on perspective. What is art? What is perfect? The “it depends on how you look at it” idea really comes into play here. Are the questions a little too deep for young readers? Maybe. Just don’t read it right before bed. You are going to want to talk about it.

Another thought provoking installment from the wonder-rich duo of Barnett & Klassen. Can’t wait for the next book to take shape!

Most everyone seems to like this board book about the person known as Square, which is also published in square format. Square is, actually, square. Square has a friend, Circle, who is a circle (We don’t get into three dimensions or the fact that each has arms, legs, etc.).

Square spends all his spare time in his “secret cave” excavating rock. The rock that he takes is always in the shape of a square (cube). When his friend, Circle, comes by one day, Circle sees a square and decides that Square is a great artist doing a “perfect self-portrait.” Circle asks square to do a similar portrait of Circle. Before Square can respond to the request, Circle is gone. Square works and works, but can’t produce a circle. This creates great anxiety. The anxious moment of Circle’s return is resolved by another misunderstanding. But Square retains some apprehensions.

My five year old found the illustrations to her liking but the plot was a bit too ethereal. We will see if her 8 year old sister sees things differently.

#1 Triangle ★★★★★
#2 Square ★★★★★
#3 Circle ★★★★★

I love Klassen's illustration style but hadn't read anything by Mac Barnett, so I figured this would be a good intro to Barnett's work, and it really was. I love these little shapes so much. They're just so funny and low-key snarky - I think I laughed more than my kid did!

Liked it better than the first. I wish they had put the trilogy in one picture book or early reader multiple chapter book. The board book format for this series isn't working for me. Board books are typically for the youngest readers. They are primarily purchased because the parents want a sturdy, colorful often classic and learning book. Babies/toddlers are into sucking, teething and chewing on board books. I get that the amazing Barnett is teaching shapes but the stories are rather sophisticated. Waiting three years for the whole story to be told is a long wait as well.

Sometimes, a book has to sit in your mind for a few days before you can really appreciate it. That’s how it was for me with Square, Mac Barnett and Jon Klassen’s forthcoming book, the follow-up to Triangle.

I came to the book expecting more mischief and sneaky tricks, and I didn’t get that at all. (Although, Triangle is noticeably absent. Who knows what happened when Square got himself unstuck from Triangle’s door. We do know that Jon Klassen doesn’t shy away from grizzly murders. Just saying. It might be worth looking into.)

We open the book and find Square free from the confines of Triangle’s door. (We can assume that he lost weight due to starvation, and eventually just fell, right?) He’s busy doing his Square thing (pushing rocks around) and Circle approaches and assumes that he’s up to something else. (We just met him, and I already like this Circle guy. He assumes the best of people.) I won’t say anything else, I don’t want to spoil it, but I will say that initially, I didn’t know what to think about it. It wasn’t what I expected. I was looking for more of the lighthearted meanness of Triangle, which I loved, and that would have entertained me, but it would really just have been Triangle II. A good second book in a series does something entirely new. Instead of that funny spite, we get kindness, a character trying to learn something new, perseverance and a big surprise.

After the seeds of the book burst open in my mind and took root, I began to appreciate Square more and more. That appreciation grew and brought me to where I am today, where I can honestly say that I love this book. It isn’t Triangle, and it isn’t trying to be. It’s Square. New, bold, and funny in a different way. Barnett and Klassen have improved the series, and I can’t wait to read this book with my students.

Still can't quite make my mind up about this series of Barnett and Klassen books.

There's a message there, existential or otherwise, I'm really not sure? They are definitely intriguing books and I like the simplistic, stylised and really quite dark illustrations.

Perplexing and thought provoking if nothing else.

I have mixed feelings about this book. After my initial reading my only thought was "Why was this so depressing?" and then gave it to my coworker to read to get her opinion. She felt that it was a downer as well.

Thinking about it past my gut feeling, I could see how there are two distinct perspectives in the book and that how we perceive ourselves is different from how others perceive us. Overall the book has potential to be too deep for children but they also can surprise you

I then gave the book to two of my 4th graders (they are voracious readers and one is an aspiring librarian) to read to get their opinions. They thought it was ok, one wasn't sure about how kids would feel about the open ended nature of the book, but personally liked it.
When asked if they thought that Square was a Genius one said that he was a genius/artist, the other said square wasn't because it was just accidents.

I will probably end up reading this book to K-6th to get their feedback, since it will probably widely vary...I'm also asking any of the regulars into the library to read it and give their opinion as well...everyone is going to read this book

A most excellent children's picture book that proves beauty, and art, is in the eye of the beholder.

I love Barnett's art, with its subtle gradations; it's simple, yet, oh, so appealing.

Busy with his daily task of pushing blocks up the nearby mountain, Square is surprised when his friend Circle happens by, and praises his genius. Having mistaken him for a sculptor, Circle assumes that Square has made the blocks in his own image, and asks him to make one in her's. Unfortunately, after a night of chiseling, Square has nothing but a pile of rubble. Or does he...?

In this follow-up to their earlier Triangle , author Mac Barnett and illustrator Jon Klassen deliver an engaging, though-provoking tale about perception, reality, perfection and doing the best you can. Square thinks Circle is perfect, Circle thinks Square is a genius, and the reality of what Square produces is viewed differently, but with equal validity, by the two. I enjoyed the story in Square more than I did in its predecessor, I think. The artwork is, as is usual for Klassen, immensely appealing, making able use of the subtle color range and bold shapes to fill out the story found in Barnett's text. Recommended to anyone who enjoyed Triangle , and to anyone looking for children's stories about differing perspectives.

Cuadrado (Square) accidentally gives his friend Círculo (Circle) the wrong idea that Cuadrado is a genius sculptor. Actually, all Cuadrado has done is to move black blocks from his cave home to a hill. Círculo asks Cuadrado to make a sculpture of Círculo, but how is Cuadrado going to manage to make this art?

Mac Barnett’s amusing picture book in Spanish will delight both children and their grownups. And isn’t art — and genius — in the eye of the beholder?

Cuadrado accidentalmente le da a su amigo Círculo la idea incorrecta que Cuadrado es un escultor brillante. Actualmente, lo único que ha hecho Cuadrado es mover bloques de su cueva sobre una colina. Círculo le pide que haga una escultura de Círculo pero ¿cómo va Cuadrado crear este arte?

Este libro de cuento ilustrado les encantarán a niños y sus padres. ¿Y no es el arte — y el genio — en los ojos de quien lo mira?

In the interest of full disclosure, I received this book from NetGalley and NubeOcho in exchange for an honest review.

Mac Barnett is a genius. Or is he really? Hahahaha!

I was hoping for a cameo from Triangle because I loved that book so much, and yet somehow, I found that this book was even more satisfying on a deeper level. I am curious how the kids will react to it. I want to read it as a companion piece and see what they think. Will they get the deeper message? Does it really matter if they don't? Hmmm. It could still be perfect in itself even if they don't.

(4 1/2 STARS) Not quite as funny as its predecessor "Triangle," but I still found this one to be tremendously enjoyable and I'm so glad I bought a copy for my bookshelf! (A+ illustrations from Jon Klassen - as always.)

I really, really like the direction this new series is taking. Behind the silly story, there are plenty of opportunities for analysis on a deeper level. Brilliant. So far, I like these better even than the hat series...

What can I say? Mac Barnett and Jon Klassen are pure genius. Circle asks Square to carve a likeness of her out of stone. Can Square pull it off???

I read this book in Dutch but am writing my review in English.

This time it is Square's time to shine! Meet Square, the number two of the shapes (with number one being Circle and we don't talk about Triangle who is just annoying :P).

We see that Square's days exist out of lugging rocks (perfectly square rocks though) up a hill next to his house. Day in, day out. I don't really understand why he is doing that, what the purpose is. Would have been fun to get more on that.

But one day Circle pops in and sees those perfect squares and, as I expected, thinks that Square is an artist and asks him to make something for her. Poor Square, we all know that he loves Circle and thinks the world of her. I do have to say, kudos that he did started to tell Circle that he wasn't an artist, but Circle had already left so no one heard. But he did do it, he did try, and that is something that is very rare in books like this. Often the characters just go for it, annoying me. Be honest!

The last few pages were just the sweetest and I was smiling. The last page however. Meh. It seems that is really part of the series to just end it in some weird ass way. I am just not a fan. Just end it normally.

The art is still one of my favourite, nice job to Jon Klassen!

All in all, I will miss this series. I can't wait what kind of books this duo will make next! And to all, I would recommend this one.

I hesitate to write too many reviews of kids books here, although I read 3x as many kids books. Because this is my thing, GR, and I don’t really want it to be one more thing I give over to kids.

But sometimes a kid’s book is just so interesting, nuanced, and wonderful that you have to tell everyone about it. And I’ll mention something I’ve mentioned in other reviews - the fact that my kid gravitates towards stories without a clear moral, that directly ask the reader questions about their perception - is one of the joys of my life right now. And this book fits in that pantheon for sure.

داستانی بود از جنس واقعیت روزمره، به شکل اشکال.موضوع بامزه ای داشت که تو درکش مشکل داشتم. احتمالا کتاب قبلی ای که از مک بارنت خوندم روم اثر گذاشته که یه همچین فکری میکنم، ولی حقیقتا امیدوارم که اون سنگ های مربعی که مربع میبره بالای کوه، جسد مربع های مرده نباشه.
مربعی که مربع ها رو بالا میبره، یه جورایی منو یاد سیسیفوس میندازه.

I love the mysteriousness within this book and its meaning. It manages to be comforting and disheartening at the same time and that is the main reason why I love Barnett's style of writing! I think it is vital to have unique picture books within children's literature that aren't afraid to be individual or different from the common literary style that are often in classrooms. The same goes for the wonderful illustrations. Klassen brings this story to life with his artwork and it suits they style of the story so well!
