I could not love this book more. It is a great SEL book, and one that will definitely add to our library collection!! Kids will easily make connections to stories like The Gruffalo or Pinocchio, but it’s a fun book all in its own way. Also would be great for the beginning of the year when classes are establishing relationships and rules. The message is simple, clear, and important, and the illustrations are awesome

Such a lovely illustrated book with a fantastic message for younger readers. I really enjoyed the book and think it can really help support younger minds understand how even the smallest of fibs can grow.

The book follows a young boy whose lies get out of control causing him to create a monster called the fib! To save his class mates he must learn a valuable lesson. A fantastic read for all ages, it would definitely be helpful in a school setting whilst teaching the importance of honesty.

I read this to my son and he was amazed by the Fib. We’ve always called lies fibs and this really opened his eyes into how big fibs can get without realizing git and how harmful they can be. I loved the way this book kid-splained for him better then I have !

The Fib is a wildly imaginative and exciting story that my children and I absolutely loved. Pedro Iniguez takes a simple fib and turns it into a magical, monstrous adventure that had us hooked from the start. The creature—with horns, claws, wings, and more—sparked so much wonder and excitement in our home.

Beyond the fun, the book shares an important message about honesty and how even small lies can grow out of control. It’s a perfect balance of creativity, chaos, and a meaningful lesson. A fantastic read that we’ll come back to again and again!

The Fib is a fun children's book that approaches the concept of telling a lie using an evolving monster that continues to grow with every lie told. In a way that is accessible to children, the author helps illustrate a "snowball effect" of telling small fibs. This is a great book to read to children to help them understand the consequences of telling fibs, with the emphasis on truth telling as the way to get out of the trouble caused by fibs. As an educator, this is a book I would read to my students.

Thank you NetGalley, Gloo Books, and Pedro Iniguez for the opportunity to read this book.

This books message is spot on. Telling a fib is easy when it begins, but it grows and grows into something you can't control. This would be a perfect message in helping a young fibber understand that their lies hurt others but how you can solve it and help it disappear. I will suggest this book to my school counselor to use with small groups, suggest to families that may have little fibbers. The illustrations of the fib help paint the picture of how large and scary telling lies can be.

A wonderful story about the "snowball effect" of what happens when telling a lie and the power of telling the truth.. The Fib is small but as it grew to the lie becomes overwhelming. A good story that children can connect to. A wonderful book for SEL lessons. In the story the FIB came due to anxiety or fear, and the teacher helped him find healthy ways to cope with these emotions.

The Fib is a wildly fun and thoughtful story about imagination, honesty, and how even a small fib can grow into something bigger than we expect. Pepe just wants something cool to share during Show and Tell, so he invents a creature with horns like a ram, claws like a bear, wings like a bat... It’s just a silly story, until that creature actually appears. And it doesn’t stop growing.
Kids will be hooked by the action and chaos (a monster loose in school? Yes, please!), but what makes this book really special is how it shows the emotional ripple of one small lie. As a parent, I loved how the story gives kids space to reflect without feeling judged. It doesn’t shame Pepe, it just gently shows how things can snowball, and that truth and courage can shrink even the biggest mess.
The illustrations are so full of movement and personality, I could almost hear the creature’s stomping feet. This is a perfect read for kids who love a little mischief, a lot of imagination, and stories that make them think.
Thank you to Gloo Books and NetGalley for the advanced copy!

You know what happens when you tell one fib after another? Well, Pepe found out in the most awful way. Pepe, a 2nd grader, had show and tell the first day of school. After all the kids went, he realized that what he brought was not cool. He pulled some lint out of his bag and said it was his special pet. He described it and his teacher said it sounded like a fib. Not knowing what a fib was, he agreed to the name. As he talked about his Fib, it kept growing and growing into a scary monster. Realizing he was wrong for lying, he began to tell the truth. His Fib got smaller and smaller. I’m not sure if Pinocchio’s nose ever got shorter, but thankfully Pepe figured it out and we don’t have scary Fibs flying all over the place.
This is a cute quick story that can be made so fun to read by using different character voices. The drawings were also cute.

It is Show and Tell day in Pepe's second-grade class, and he courageously brings one of his drawings to share with his classmates. However, after hearing about other children's toys, gifts, and objects, Pepe feels a wee bit insecure about his drawings, so….he lies and tells his classmates that he has a mysterious pet in his pocket (it's actually a piece of lint). The children don't believe Pepe and say to him that his pet is nothing but a fib. Not knowing what fib is, Pepe tells the children that his pet is, in fact, called  Fib. Soon, Fib grows larger and larger until it becomes unmanageable, and Pepe has to admit that he made up the story of the Fib. 
This is a charming story with the most delightful pictures that will surely captivate and intrigue young readers. The story gently teaches about telling lies and the hurt they can cause, using the ingenious metaphor of a pet made out of lint.
With its engaging narrative and valuable lesson on honesty, this book is a perfect addition to any elementary classroom. It comes out in October 2025, and I highly recommend it to elementary teachers.

I read The Fib with my 5-year-old, and we both thoroughly enjoyed it! The illustrations are absolutely fantastic—bright, engaging, and they flow perfectly alongside the story. One of the things I appreciated most was the representation: a variety of ethnicities are featured, allowing every child to see themselves reflected in the story.

The way the book explains how a simple fib can spiral out of control is brilliant. It opened up such a great conversation between us about honesty and how our words can have consequences. My son was completely captivated and has already asked to read it again.

This is a beautiful, meaningful book we’ll definitely be adding to our bookshelf when it’s released. Highly recommended for young readers and families!

This book will help children to understand what happens when they tell fibs, and how it can hurt people. I really liked the colour pallet used within the illustations.

This book is really great. My elementary-aged kids really enjoyed it and I loved the message behind the book. It was imaginative and fun. The illustrations were great, too! Would definitely recommend,

A truly Great age appreciate story about how fibs keep growing and growing. All kids “fib” but what of your fib grows and grows into a… monster.

*The Fib* by Pedro Iniguez is a simple yet impactful story about a second-grade boy named Pepe and the fib he tells. What starts as a small and harmless lie quickly grows bigger and scarier as Pepe tells more and more fibs. The fib becomes so large that it becomes a monstrous presence in the classroom, causing trouble for everyone. Luckily, Pepe's teacher helps him understand that the only way to stop the fib from taking over is to tell the truth. Eventually, the fib shrinks back down to a small size and disappears altogether.

This book serves as a great morality tale that even young children can easily grasp. It teaches an important lesson about the consequences of lying and the value of honesty. The illustrations are vividly colorful and engaging, though they have a simple style that suits the story well. Overall, it's a wonderful book for teaching children about the importance of telling the truth. I would give this book 4 out of 5 stars.

My Children loved this book! they asked for it reading night after night and especially enjoyed the description of the fib as it was read in a catchy repetitive fashion. The story is great, engaging, enjoyable and most of all brings a lesson to learn with it.

Such a fantastic and funny story that shows just how wild things can get when you tell a little fib—and how honesty really is the best policy! The illustrations are vibrant, the story is super engaging, and I just know kids are going to love it. Honestly, I would’ve been obsessed with this book as a kid!

Thanks NetGalley for the ARC!

I received an ARC of this children's book from NetGalley in exchange for an honest review.

This is a wonderful book with a very important message told in a way that children can understand and relate to. And the pictures are great too!

I truly enjoyed reading this book to my children. It had an overall message that was easy enough to explain but wasn't out right obvious. The story kept us engaged and the illustrations were very vibrant and fun. I would definitely recommend this book for anyone with small children.

Imaginative, fast paced, and SO deliciously fun!

I can't stop smiling about this picture book. It's got everything in abundance... a clever message, lots of fun along the way, and the all important takeaway message - the importance of honesty and how little fibs can grow out of control.

It's a lot of fun to read out loud, and the striking illustrations make it exceptionally memorable. We especially like the evolution of the Fib, and love how it goes from being super cute to quite a scary monster - reflective of an out of control lie. I imagine loads of parents will be having a good old giggle, while wide eyed little ones will be gasping in delight. Even my 12 year old was gripped!

Love it! Definitely one that will be read over and over again.
