An adventure novel is a story about somebody going on a big, exciting journey with lots of challenges, danger, and excitement along the way. It's like playing make-believe in your head and pretending you're exploring a new land or fighting bad guys. You might be reading about pirates sailing the high seas, explorers trekking through the jungle, or detectives solving mysteries in exotic places. When you read an adventure novel, you get to imagine that you're right there with the characters, experiencing all the thrills and danger yourself!
