you can break “I like mystery books” to at least two ideas: 1. if you like reading (and why they will enjoy this book for it being so captivating, etc.), 2. mystery book and how it is an exceptional novel, 3. it will teach them many new things they didn’t know before and that were quite interesting (I haven’t read the book but there are interesting things you learn in every book), and you can also add 4. it will take them to a whole new world where they will forget about everything around them
