The ChronoStone Saga · Series 1: The Earth Chronicles

Two kids. One dog. All of history.

When Ethan and Maggie Carter find a glowing stone pedestal in the cave behind their new house, history stops being something in a book. It becomes a place they can visit, from the last days of the dinosaurs to the night people first walked on the Moon.

The Time Map

Where will the Stone take them?

Twenty stops across 66 million years. Tap any stop to meet that book.

Adventure on every page. Real facts too.

Kids read ChronoStone for the dinosaurs, the storms at sea and the secret chambers. Without noticing, they learn how the past really worked.

Real history, honestly told

The pyramids were built by organized, well-fed work crews, not slaves. King Arthur is a legend, and the book says so. Hard history is told gently and truthfully, for young readers.

Maggie's Field Notes

Short, kid-voiced fact boxes in Maggie's own handwriting, each one backed by a real source that grown-ups can look up.

Heart, humor & a very good dog

A wisecracking big brother, a sister who has to know everything, and Rex, who chases anything that moves, even across time.
