What makes The Borrowers Avenged a Fantasy book?

You're likely referring to "The Borrowers," a series of children's fantasy books by Mary Norton. While there is no book specifically titled "The Borrowers Avenged," the series features elements that clearly place it in the fantasy genre. Here's why:

* Magical Realism: The Borrowers are tiny people who live secretly in the walls and floors of human homes, borrowing objects from their human neighbors. This concept, while fantastical, is presented with a level of realism that makes it believable within the book's world. This is a key element of magical realism, a genre often found in fantasy.

* A Different World: The Borrowers have their own society, culture, and way of life, distinct from the human world. Their world is a miniature version of the human world, filled with its own challenges and dangers.

* Mythical Creatures: Though not explicitly mentioned, the Borrowers themselves can be considered mythical creatures, adding a fantastical element to the story.

* Exploration of Themes: The Borrowers series explores themes of survival, courage, friendship, and the importance of community, common elements found in fantasy literature.

While not explicitly "epic fantasy" with grand magic systems and epic battles, the series relies on imaginative concepts, believable worldbuilding, and fantastical creatures to create a captivating and unique world, firmly establishing it within the fantasy genre.
