Ellie Ment and the Material Matter - Low Res.jpg

The gold standard in book reviews since 1933

“A quirky science adventure with an engaging message of sustainability and hope.

 

Effectively blends environmental science, mystery tropes, and discussions of ethics in this story for STEM-focused middle-grade readers.

 

The narrative handles the complexities of trying to save the world with nuance and care."

15 - Kirkus_edited.jpg

"This playful novel—set in England’s picturesque small-town of Hapsie—recalls Harry Potter and
Hogwarts, but instead of magic, science unites the story.
Ellie’s experiments and discoveries offer
opportunities for the heroine to break into explanations about the scientific principles involved."

"There’s much to appreciate about this purpose-driven book. Along with a valuable STEM focus, the
story is creative
, and Ellie’s fierce stubbornness and willingness to go head-to-head with adults
makes her a strong role model."

4 out of 5

"The book is a one-of-a-kind children's book that teaches children to use their knowledge for the greater good, like protecting our environment from pollution of any kind. 

I honestly couldn't find anything negative about the book. It delivered exactly what I expected."

One of Stephens’s standout themes is the tension between idealism and pragmatism in environmental action.
 
The narrative challenges readers to consider whether compromising ethics for the greater good is justifiable, a question that resonates deeply in today’s climate crisis. Stephens also excels at making science accessible and exciting, seamlessly integrating important learning concepts into the plot to inspire curiosity in young readers."

"Ellie Ment and the Material Matter is a brilliant fusion of education and entertainment, making complex scientific concepts accessible and exciting through Ellie’s infectious enthusiasm.
 
Bertie Stephens’ storytelling, paired with a cast of relatable characters, creates a narrative that is both thought-provoking and laugh-out-loud fun.
 
The environmental themes, underscored by the Clean Planet Foundation’s mission, resonate deeply, urging young readers to question systems and take action.
 
I highly recommend this book to young readers and adults alike who love science, adventure, and stories that inspire courage and curiosity.
 
The story blends quantum physics, environmental activism, and youthful rebellion, and leads to a thrilling cliffhanger with a neon green sky.
 
This is a must-read that will leave you eagerly awaiting Ellie’s next move. Ellie has more adventures to come!"

Ellie Ment and the Material Matter: The Science Book Your Child Will Actually Want to Read

By Timothy Arden

"Smart, funny and grounded in real science, Bertie Stephens’ novel is a gripping eco-mystery that helps children connect the dots without ever talking down to them. It’s a book that opens the conversation about science and environmentalism...

​... Plenty of books try to tackle the subject, but few treat children as if they’re genuinely capable of grasping real science—and even fewer manage to make that science exciting. Ellie Ment does both. In fact, it’s the rare children’s book that manages to be educational, gripping and laugh-out-loud funny all at once."

...If you’ve ever wondered how to talk to your children about plastic waste, climate change, or why grown-ups always dodge the big questions, this book does it. It even makes quantum relativity sound like something you’d chat about over breakfast. Every school should have a copy. Every kitchen table should have a child reading it."

"Okay, so first things first: this book is a blast.

 

Ellie Ment and the Material Matter isn’t your average “kid genius saves the world” story. It’s fun, it’s quirky, and it somehow manages to sneak real science lessons into a story that never feels like homework."

Bottom line? Ellie Ment and the Material Matter is smart, funny, and way more exciting than I expected. It’s the kind of book I’d happily pass along to my younger cousins, but also one I had no problem enjoying as a grown-up who just likes a good adventure."

“Ellie Ment and the Material Matter succeeds in something rare: it makes science feel exciting without being intimidating...

...A delightful blend of adventure, science, and environmental awareness. At its heart, this is a book about curiosity and the courage to ask questions… an invitation to young readers to see wonder not in the fantastical, but in the tangible mysteries of the natural world.

Children will enjoy the quirky adventures, the jam-jar experiments, and the mysteries Ellie stumbles into, while adults will appreciate the gentle encouragement to nurture curiosity and responsibility in the next generation."

 "a perfect blend of fun, informative, and timely."

"ELLIE MENT is also just plain fun. The text crams in a lot of adventure: a mysterious set of gauntlets that grant power over elements; an inciting mystery that can only be solved with knowledge of chemistry; a secret society with a vast underground lair...

... ELLIE MENT is exciting, funny, and charming. However, at its heart, it’s a call to action—to stand up, to be our best selves, and to stand together to tackle the challenges we all face in the current moment.
