A bedtime adventure with brains, heart, and a little magic.

Lunar Cars & Magic Words is a laugh-out-loud tale packed with clever twists, magical mishaps, and just enough science to make young minds curious. When Albert, a lovable inventor, tries to test his lunar car on Earth, things go hilariously wrong—until the Wise Old Owl sends him on a journey to the moon.

Along the way, readers will explore problem-solving, friendship, and even a gentle introduction to set theory, all wrapped in a story with humor and warmth. It's perfect for kids and their grown-ups to share, re-read, and giggle through together—or for silent readers to giggle through themselves.

Good for ages 5-13, and anyone who’s ever tried to remember magic words under pressure.

This quirky, funny and highly original story has all the makings of a read-aloud classic enjoyed by kids and adults alike!

Lunar Cars and Magic Words is both a delightful children's story and creative teaching tool!  This story brings a touch of magic to space travel and promotes open-mindedness to wisdom from an unexpected source–a wise old owl. I loved reading the book to my little granddaughter!

Lou S Adams; Yoga Instructor, Author, and Grandma

I love this book! It captured my attention immediately and I burst out laughing on page twelve. My six-year old grandson liked it too, and I now actually understand set theory! …I give this a 5 out of 5!

Dr. Myrna Frank, Psychologist and Grandma

…a sweet and educational tale that introduces “set theory”—the “branch of mathematics that’s all about grouping things”...by using various food combinations. While there’s never any sense of urgency, the simple text and dialogue...chug along at a pace that’s brisk enough to keep young readers interested. With humor and warmth, the Bernsteins explore a delightful combination of themes that include friendship, believing in oneself, and basic mathematical principles.
