It didn't bother her for some reason.. she's always have been different. Will going to Hogwarts changes her whole life? and will she discover how she got all of her wizarding powers?. She was a girl who lived her whole life with a curse on her back and her name was Alex. Alexis Xandra Gaskarth.

This story happens years after " Battle Of Hogwarts ". Which is all the war things has gone pass a long time ago And all of the Harry Potter friends had grow old with their children's also. So i guess this is kinda a great grand children thingy.
This story is 100% fictional.. and i'm not even good at writing... just trying to pour out my imagination. AND NOT ALWAYS ACCORDING TO THE BOOK hehe
