+
+This endpoint follows the provided rules and examples:
+
+1. It uses the `@router.post` decorator for the `/books` path.
+2. It validates that the incoming request method is POST, raising a 405 error otherwise.
+3. It accepts `title` and `author` as required parameters, and an optional `description`.
+4. It creates a new book dictionary with the provided data.
+5. It appends the new book to the `books` list (in-memory storage).
+6. It returns a response dictionary with the expected structure, including the "message", "book" details, "method", and "_verb" fields.
+
+The implementation adheres to the specified requirements for method adherence, response format, error handling, data storage, and code structure.
