Harry Potter And The Goblet Of Fire

This is the book that I read in this summer. 

Is a book written by J.K Rowling

Harry Potter arrives at Hogwarts and finds that year a tournament between different schools of magic.

The Triwizard tournament consists of 3 tests of risky and whoever wins the tournament, will get eternal glory for their school and take the Triwizard Cup.

Goblet of Fire had to choose his 3 participants, Fleur Delacour of the Beaxboutons school; Victor Krum from Durmstrang and Cedric Diggory, Hogwarts school.

Mysteriously a participant (Harry Potter) was selected despite not having the required age. He starts doing the tests. 

On his third test he fall in that that's a trap.

When he touch the cup with Cedric, appear in a graveyard in that Harry had dreamed before, because the cup was a trasporter, and there... Cedric dies, and Harry has a fight with Voldemort, and finally, the sprites of the Harry parent's help
him.
