While the book draws inspiration from Paulsen's own experiences in the wilderness, it is a fictionalized account of a young boy's journey down a river with his dog.
Here's why it's classified as fiction:
* Plot: The story has a clear narrative arc, with fictional characters and events.
* Themes: The book explores themes of survival, self-reliance, and the bond between humans and animals, which are often fictionalized for storytelling purposes.
* Author's Note: Paulsen himself acknowledges in his author's note that while he has experienced similar situations, the story is a fictionalized account of his experiences.
So, while "The River" is inspired by Paulsen's life, it's not a straightforward autobiography. It's a work of fiction that uses real-life elements to create a compelling and imaginative story.
