Fantasy
Why does Winky the house elf save a seat for her master who never comes? You can find out in Harry Potter and the Half Blood Prince, by J.K. Rowling. My favorite part is when Hermione found out who the Half Blood prince is because, Hermione found it in a old Daily Prophet in the library, and I never knew that the library had them. If you like fantasy, I recommend this book to you.
