Today is an exciting day!
During our presentation at the Great American State Fair, we unveiled something we’ve been eager to share with families across the country.

The Secret of the Forgotten Rebel is the first book in the new Harper Kids Mystery Series, and it’s the beginning of an exciting new way for children to discover America’s history through mystery, adventure, and the remarkable stories of our Founding Mothers.
If you’ve ever wished there was a book that could get your kids excited about American history without feeling like another textbook, this series was written with your family in mind.
History Was Never Meant to Be Boring
Children are naturally curious. They love solving puzzles, uncovering secrets, and asking questions. So why not use that curiosity to introduce them to the people and principles that helped shape America?
The Harper Kids Mystery Series follows siblings Abby and James Harper as they stumble into mysteries that uncover the remarkable stories of America’s Founding Mothers—women whose courage, wisdom, and sacrifice helped build our nation but whose stories are too often overlooked.
Each book combines mystery, adventure, humor, and authentic history to create an engaging reading experience for boys and girls alike.
The Secret of the Forgotten Rebel
In the first adventure, Abby and James are excited to finally settle down after years of moving with their military family. But their fresh start quickly turns upside down when priceless Revolutionary War artifacts disappear from a local museum—and suspicion falls on their own family.
Determined to clear their mother’s name, the siblings begin investigating the mystery themselves. Along the way, they follow hidden clues, crack secret codes, meet unforgettable characters, and uncover the incredible story of Mercy Otis Warren.
Many of us grew up learning about the Founding Fathers, but fewer know about the women who also played an important role in America’s founding. Mercy Otis Warren was a playwright, poet, historian, and political writer whose words encouraged the cause of liberty and helped shape public opinion during the Revolutionary era.
Her story reminds us that courage doesn’t always look the same. Sometimes it means speaking truth, standing for what is right, and using the gifts you’ve been given to make a difference.
More Than Just a Mystery
At Moms for Liberty Foundation, we believe one of the greatest gifts we can give our children is an understanding of our nation’s history and the principles of liberty on which it was founded.
That doesn’t have to happen only through history lessons or memorizing dates.
Sometimes it starts with a great story.
Our hope is that families will read these books together, talk about the characters, ask questions, and explore the real history behind each adventure. Along the way, children will encounter timeless lessons about courage, teamwork, forgiveness, critical thinking, and the freedoms protected by the Bill of Rights.
Most importantly, we hope they’ll discover that history isn’t just something that happened long ago—it continues to shape the world they live in today.
Start the Adventure
Whether your child already loves mysteries or simply enjoys a good story, we hope The Secret of the Forgotten Rebel becomes a favorite on your family’s bookshelf.
This is just the beginning. More mysteries—and more remarkable Founding Mothers—are waiting to be discovered.
