When twelve-year-old Juno Jones follows her friends into a mysterious cave hidden in the woods outside Riverview, she's expecting nothing more exciting than a cool refuge from the summer heat. What she and her friends—history buff Max, quiet nature expert Ren, and brilliant engineer Harper—discover instead is an ancient device that hurls them back in time to Ancient Egypt.

Suddenly, they're over 4,000 years in the past, surrounded by workers building the Great Pyramid of Giza. With no idea how to get home and only each other to rely on, the four middle-schoolers must navigate a world where modern knowledge meets ancient suspicion. Their only guide? A strange mechanical owl named ECHO with more secrets than answers.

But they aren't the only time travelers in Ancient Egypt. A mysterious corporation called Tempus is altering history for their own gain, and their changes could have catastrophic effects on the future—including erasing the kids' very existence.

Now, Juno, Max, Harper, and Ren must find the courage and ingenuity to stop Tempus, protect the timeline, and find a way home. Their journey will test not just their knowledge of history and science, but the strength of their friendship and their own hidden potential.

In this first adventure of the Time Guardians series, four ordinary kids discover that they might be the only ones who can protect the past, present, and future. Because sometimes the most important moments in history aren't the ones in textbooks—they're the ones no one ever sees.

The Secret of the Chronos Cave combines pulse-pounding adventure with fascinating historical detail, introducing young readers to Ancient Egyptian culture, the engineering marvel of the pyramids, and the ethical questions that come with great power. Perfect for fans of Rick Riordan's mythology adventures and readers who have grown beyond Magic Tree House but still love time travel stories.

Store Description

We first started out as ?The Paperback Exchange,? a chain of physical bookstores where we would part exchange your beloved books for new stories to transport you to faraway places. However, as shopping started to evolve to online shops and marketplaces, we bid our stores goodbye to become ?PBShop.?

We pride ourselves in being a community of local book lovers which allows our passion and devotion to shine in everything we do. In 2020 we not only celebrated our 20th birthday but our 1st birthday as being completely employee owned after becoming an E.O.T in September 2019. We are proud to be different and embrace standing apart on a book mountain by working from a virtual inventory which allows us to provide thousands of books that may be difficult to get for your bookshelf or your studies. Working with a number of different suppliers allows us to explore other avenues such as puzzles, sheet music and even stationery so we really do have something for everyone. Life is about being versatile in all realms of existence. If this is your first visit or you are a returning customer, we would like to welcome you to the PBShop family, for there is no friend as loyal as a book.
