The Harry Potter series (系列) is my favorite book series. I am fascinated by (着迷于) every character and every plot (情节). There are seven books in the Harry Potter series. The first six books take place (发生) at the Hogwarts School. They’re about Harry’s school life. The seventh book tells the story of Harry looking for Horcruxes (魂器) outside of school and destroying Voldemort.
