I do usually not write reviews here on ficwad... But this story turned out so great that I have to share my opinion.
The story is a time-travel type. But it is very original and unique in its execution!
It does not make the mistake to rewrite the original books. No, it takes off on its own, even before Harry gets to Hogwarts and follows multiple characters with each their angle to the story... Mostly Charlie Weasley, N. Tonks, Dumbledore, a likable Telawney and many more.
If you read this and have not read anything of the actual story yet. I strongly recommend that you start reading - now.
