The  Dark Mark is a sign the shows the Death Eaters that there Lord has risen, or Master.  After the game the Dark Mark is shown and there is now a crowd of Death Eaters that are there to kill Muggles (human that are not wizards), Mudbloods (human that are wizards or witches) (also a dirty name for them), and wizards that are not pureblooded.  After summer holidays are over harry goes back to school on the Hogwarts Express.  When Harry is back at school, during the welcome back feast he finds out there is no such thing as a Quidditch team.  Quidditch has been replaced by a triwizard contest. 

     The triwizard contest is between three witches or wizards.  Harry is put into the contest by someone who put his name in a magical name telling cup just for the triwizard contest. T he person who put Harry's name in, it came out.  Harry was the last name to be called out of the cup.  Now harry has to complete three different tasks.  This was the best book I've ever read.  I rate this book a 10 out of 10. I recommend this book to ages 12 and up.  This book is a science fiction and fantasy.
