While they feature fantastical elements like time travel and magical trees, the stories are set in specific historical periods and accurately depict the time period, culture, and historical events.
Here's why:
* Historical Setting: Each book takes place in a different time period and location, from ancient Egypt to the American Revolution.
* Historical Details: The books include detailed descriptions of the clothing, customs, architecture, and everyday life of the time period.
* Historical Figures and Events: The books often feature real historical figures and events, which are generally portrayed accurately.
While the books are primarily intended for children, they provide a fun and engaging way to introduce them to history.
