Help Looking For story

by GhostWriter2545

Series of stories where: Harry goes to the Department of Mysteries, dates a vampire,Cho and hermoine. He ends up getting a globe thing during the summer that other people want. He goes to Beauxtobons for a dance and saves them, Cho ends up cheating on him. Harry plays professional quidditch. Its a good story just can't find the series.

Sorry for this but I am looking for a series of stories

It starts with Harry going to the department of mysteries one summer to train.

The first story Harry is paired with a vampire, then later on in the series he is paired with Cho. That doesn't end well.

Hogwarts ends up being on good terms with Beauxtbons for some reason and they go to a dance over there which harry helps protect the students. T

There is also a part where Harry gets a couple of spells to control giants.

If you can find it let me know. Thank you.
