2. Characters: Are the characters well-developed and relatable? Do you care about their journey and what happens to them?
3. Writing style: Is the writing clear, engaging, and well-crafted? Does the author have a unique voice or style?
4. Theme: Does the book explore important or thought-provoking themes? Does it leave you thinking about the story long after you've finished reading?
