While the story touches on serious themes like war, loss, and separation, the focus is on the relationship between a young boy and his fox, making it suitable for a younger audience.
Here are some other genres that could be applied:
* Animal fiction: The story centers around Pax, the fox.
* Adventure: The journey Pax and Peter take is full of adventure and excitement.
* Coming-of-age: Peter's journey through hardship and separation helps him grow and mature.
Ultimately, "Pax" can be enjoyed by a wide range of readers, but its core themes and engaging narrative make it a strong choice for children's fiction.
