Harry Potter & Little Alexa

"She's just a 5 year old mud blood with an extremely amount of magic in her small body" said Minerva to Albus "should we bring her to Hogwarts , Albus? Does she even knows about this?"
"We should act before Voldemort can reach her and lead her into the Dark Side" said Dumbledore "send her the card"

Little they knew that Alexa was already studying all the advanced spells and charms, historic facts about hogwarts and she could tell you all the magical creatures in alphabetical order, plus she will carry her "Hogwarts, a history" book everywhere she went.
With her muggle parents, muggle school and everyone scared of her, Alexa's life was really sad and lonely. Until one day an owl with a card on its beak deliver a card that will change her life forever, but maybe things will not go as intended.

Alexa will meet Harry, Hermione, Ron and many other classmates , some good and some bad.
Apparently Alexa entered Hogwarts at one of the worst times, Umbridge is taking all the fun and magic away from Hogwarts and Voldemort is back again, more powerful than ever because now he got his old allies back.
But will Harry be able to defeat Voldemort this time? Will Alexa just stay at Hogwarts safely or put her whole life in danger? Will new mysteries be discovered?
