Book cover of The Bad Guys

Chrissie Krebs Author Of Bizard the Bear Wizard

From my list on graphic reads for young reluctant readers.

Why am I passionate about this?

As a child, I was obsessed with comics, whether it was Garfield, Calvin and Hobbes, or the Far Side, I would devour every one I could get my hands on. I discovered the joy of observing two storylines – the one the writing was telling me and one that the pictures were telling me. As I became a teacher, I realized the importance of pictures and stories working together to keep students engaged. The resurgence of graphic novels has now been a focus for me in my pedagogy practices as well as my pathway as an author-illustrator. 

Chrissie's book list on graphic reads for young reluctant readers

Chrissie Krebs Why Chrissie loves this book

The Bad Guys series which chronicles the adventures of some stereotypically dangerous animals trying to do good and save the world pulled me in from page one.

You have humor (especially around bodily functions which always gets a giggle) and well-developed characters that are oftentimes naughty but incredibly likable. In the first episode, the book has been broken down into manageable chapters, the dialogue is not too lengthy and the high-paced illustrations communicate action and humor perfectly.

Young readers will certainly feel accomplished after completing this 144-page graphic novel.

4 authors picked The Bad Guys as one of their favorite books, and they share why you should read it. This book is for kids age 7, 8, 9, and 10.

Book cover of Lunch Lady and the Cyborg Substitute: Lunch Lady #1

Ken Lamug Author Of Born to Be Bad

From my list on unexpected superheroes.

Why am I passionate about this?

I am a professional dabbler who has tried things from beekeeping, duck herding, race car driving, coding, and filmmaking. But I am famously known as the author and illustrator of imaginative and fun children’s books and comics. My latest book is the hilarious supervillain graphic novel Mischief and Mayhem. It’s a story about Missy who gets kicked out of superhero boot camp and ends up as a supervillain (a nice and friendly one). I’ve always enjoyed reading about unexpected heroes and characters who flip the script. We all have challenges in our lives and when we face them head-on is when we truly find the heroes in ourselves.

Ken's book list on unexpected superheroes

Ken Lamug Why Ken loves this book

The place you least expect for a hero to turn up is the lunchroom and that’s exactly what we get here. In this issue of a long-running series Lunch Lady and Betty, her assistant, investigate the strange case of a missing teacher, a creepy substitute, and how this all connects with the Teacher of the Year award. Scenes in the story revolve around the school which will make it relatable to school-going readers. Kids will have a new respect for people around them as they identify who could potentially be a hero in their own small way.

Little do they know, Lunch Lady doesn’t just serve sloppy joes—she serves justice! Whatever danger lies ahead, it’s no match for LUNCH LADY!


Book cover of Meet the Bigfeet

Travis Nichols Author Of A Witch's Last Resort

From my list on friendly freaks, monsters, and cryptids.

Why am I passionate about this?

I’m a lifelong monster fiend. I love horror and sci-fi, and I especially love stories that really dig into characters and how they smash into each other. My favorite scary books (and movies, etc.) are funny, and my favorite funny books are kinda scary. It can be super healing and empowering to read books about terrible things that are handled with a heaping scoop of empathy and humor and absurdity.

Travis' book list on friendly freaks, monsters, and cryptids

Travis Nichols Why Travis loves this book

Cryptids? Gnomes? Maps and charts? I’m in heaven.

I don’t know Kevin, but he feels like a kindred spirit who grew up on the same set of references. The Yeti Files books are hilarious and cool with a huge cast of cryptids (check the endpapers for a roll call). Marlon the skunk ape is my favorite.

I love the way the story of Blizz attending his family reunion and thwarting George the cryptozoologist is told: illustrated spreads, whooshing panels, Indiana Jones-esque dotted line traveling interludes, etc.

The rhythm and pace surf you from page to page. Reluctant readers don’t stand a chance.

Book cover of Real Pigeons Fight Crime

Kate Temple Author Of The Underdogs Serve It Up

From my list on hilarious animal characters.

Why am I passionate about this?

I am a big fan of two things… one is graphic novels and the other is funny stuff! When those two things come together I am in my zone. I read lots of graphic novels when I was a kid and I've never really stopped. They are a great part of anyone’s reading diet. Now I write funny graphic novels for kids with my writing partner Jol. We’ve written 20 books to date including The Underdogs series, but there’s more to come!

Have you even noticed how pigeons are everywhere and we don’t really notice them?

Wouldn’t they make the best spies and the best crime fighters? Well the authors of this book think so and so do I.

Book cover of The Stonekeeper

J. C. Phillipps Author Of Pacey Packer Unicorn Tracker

From my list on young readers featuring a strong female protagonist.

Why am I passionate about this?

I loved graphic novels even before I became an author/illustrator. But because I create for young readers, I also read a lot of graphic novels aimed at them. I am also a big believer that books with female protagonists are important for all readers: male, female, and non-binary. All of the books I’ve recommended are books I plucked off my own bookshelf, and that I’ve read several times and I think are exceptional in some way.

Amulet is a masterwork of story, imagination, and art.

Tragic circumstances lead to Emily, her younger brother, and her mother having to move into the run-down home of a relative. While cleaning, Emily uncovers an amulet, which almost seems to be meant for her.

That night, her mother is kidnapped by a monster and in order to rescue her, Emily and her brother rush through a portal into another world. And that’s just the beginning!

Emily is a strong young woman who makes bold choices and fiercely defends her family. This adventure story is epic!

Book cover of X-Men: The Mutant Empire Omnibus

Percival Constantine Author Of Heroes Forged

From my list on superheroes that aren’t comics.

Why am I passionate about this?

For as long as I can remember, I’ve been fascinated by superheroes. Maybe it’s because as a bit of an outcast myself growing up, I gravitated towards stories of people who were outside society, yet actually more powerful because of it. Perhaps I’m drawn to the idea of people who work outside the system to make the world a better place, regardless of if it’s dangerous to them or if they don’t reap any kind of personal reward. Or maybe I just like to watch beautiful people in colorful costumes beat the crap out of each other. You can always listen to me on the Superhero Cinephiles podcast to hear me talk more about superheroes.

If you were a fan of the X-Men animated series, then this next pick is the book for you. Magneto and his followers take control of a fleet of the mutant-hunting Sentinels with the express purpose of establishing a new mutant nation. Naturally, the X-Men have to stop him, but with half the team on a mission in space, that’s a tall order. Golden writes a story that’s perfect nostalgia bait for anyone who loved the 90s X-Men.

Book cover of Love, Z

Linda Zajac Author Of Robo-Motion: Robots That Move Like Animals

From my list on robots for little kids with big-tech taste.

Why am I passionate about this?

I’m fascinated by robots. As a former computer programmer, systems analyst, and consultant, I’ve had an interest in technology since my first programming class in high school. I’ve been to robotics labs in Boston, Massachusetts, and Lausanne, Switzerland. My husband is a mechanical/software engineer, so STEM is a big part of our lives. In addition to Robo-Motion, I’m the author of a number of Minecraft books with STEM and coding sidebars. I’ve also published many magazine articles, one of which was the inspiration for this book. I wrote about the CRAM cockroach robot for the March 2017 issue of MUSE.

Linda's book list on robots for little kids with big-tech taste

Linda Zajac Why Linda loves this book

I was immediately drawn to this title because my last name starts with a “Z,” which means I’m always last. Z is an adorable young robot, who wears pajamas and a sailor’s hat. I love all the subtle, but meaningful touches in the illustrations: the partial glimpse of what Z has packed, letters on the robots, the cat that makes itself at home, and the hats that change heads. This is the kind of book I would have loved reading to my kids. With its peachy cover, this sweet story is as warm as a hug.

By Jessie Sima ,

1 author picked Love, Z as one of their favorite books, and they share why you should read it. This book is for kids age 4, 5, 6, and 7.

What is this book about?

Book cover of Annie Bot

Olivia Alder Author Of Highly Compatible

From my list on Silicon Valley: sex, power, technology and ambition.

Why am I passionate about this?

I’ve worked in technology for more than a decade, living and working in Silicon Valley, where ideas that sound futuristic can feel inevitable and only a heartbeat away. It can sometimes feel strange, being surrounded by people building the next big thing while still wondering what any of it will actually mean for people, relationships, and society.

That tension is why I write near-future fiction. I love books with big ideas, but I also want heat, romance, ambition, and messy human choices. I’m drawn to stories that bring those worlds together—and ask what happens when the future arrives before we’ve figured out what it means for us.

Olivia Alder Why Olivia loves this book

I’m fascinated by the ways AI and intimacy are becoming intertwined.

We already trust AI with our deepest thoughts, questions, and secrets. Increasingly, people are forming intimate relationships with this software that knows them so well. The more it learns about us, and the better it becomes at anticipating what we want, the more complicated our ideas about desire, consent, and control become.

Like my book, Annie Bot asks whether a choice can truly be yours if someone (or something) has been designed to shape it. If technology can influence or even manufacture desire, what does consent look like?

4 authors picked Annie Bot as one of their favorite books, and they share why you should read it.

Book cover of How to Code a Sandcastle

Vicky Fang Author Of Invent-a-Pet

From my list on inspiring girls in STEM.

Why am I passionate about this?

I love encouraging kids to explore engineering, design, and technology! I am a former Google product designer for kids and families. I started writing to address a growing need for coding education, particularly for girls and kids of color. Stories are a wonderful way to demonstrate concepts and to invite kids to approach STEM with creativity and imagination. I picked a range of books for this post, from non-fiction to fantastic, because different kids will respond to different kinds of stories. Through these books, I hope that kids will find inspiration and tools for creative problem-solving, for STEM and beyond.

There are a lot of humorous mishaps along the way, but just when it looks like the sandcastle might never get built, Pearl uses her coding skills to save the day and create something even better: a gorgeous sandcastle kingdom!

Book cover of Leo Gray and the Lunar Eclipse

Evonne Blanchard Author Of Amelia, the Merballs and the Emerald Cannon

From my list on space books that will launch your kids into orbit.

Why am I passionate about this?

I’m a science fiction and fantasy children’s book author, who loves everything about space and science fiction. I’ve been fascinated by space ever since I was little; mesmerized by clips of Neil Armstrong and Buzz Aldrin walking on the moon. As a teenager, War of the Worlds by H.G Wells was my favorite book! My daughter’s complete lack of interest in space inspired me to write a space adventure series. How could I make space entertaining? When it comes to children, I’m a big fan of mixing space facts with a dollop of space fiction, so I hope you will enjoy the collection of books on this list!

Poor Leo has to wear century-old outfits and live in a house full of ancient clocks and TVs. Meanwhile everyone else zips around on flying cars and wears the latest electronic clothes. Leo is desperate to win a science competition so that he can attend the lunar academy on the moon, but his Dad is equally determined to keep him here on earth. Twists and turns abound. Why are the trees disappearing? What about those mysterious aliens the Lunalings? Leo will uncover the truth. But will he have enough time to save Earth from destruction?
