✔ 最佳答案
1. I think A Series of unfortunate events is easier for the author always explains the hard words.
2. I think Harry Potter is definitely more interesting, because it includes magic and wars and really facinating plot.
3. That I really don't know, maybe you can check on Amazon or somewhere like that. If you want to be environmental-friendly, I suggest you to borrow it from the library, it cost $0 (except you return it after the due)
