Heir of slytherin, he is not, or is he?

Sabrines POV

The dia my letter came through the door, I knew I was one of the lucky few going to Hogwarts, the BEST Wizardry school in our land,
By our land, I mean of course us witches and wizards, excluding all the muggles. But I can’t say much about Muggles, for I am half a muggle.
My father died when I was 7, but I know he was a full Muggle, whilst my Mother was a Witch, a pure blood.
My mother had to hide the fact that he was a Muggle, and when they got married My grandparents went out the picture and refused to ever see me, her or my father again.
But anyways, onto the mais exciting stuff!...
