The Golden Quartet: Year 4

Astrid Black is entering her fourth year at Hogwarts with her three best friends, Harry Potter, Hermione Granger, and Ron Weasley.
Athena puts her faith (and gold) in the hands of Fred and George, Death Eaters make an appearance at the Quidditch World Cup, and Hogwarts decides to host the Triwizard Tournament.
Astrid is shocked (as much as anyone else) when her best friend, Harry's name is called to compete in the tournament. The rules are strict and all Astrid can do is sit in the stands and hope Harry can survive on his own.
But Harry's safety won't be the only thing Astrid will be worrying about.
