I would like to recommend you all a Harry Potter Fanfiction.
Harry Potter: Return From Future by Veil_Writer.
Please search for the book add the book to your collections and show some support. I have read the fanfiction (much ahead of what it has been published this time) and it was a very good story premise.
I would have recommended the book in author's note but it seems as if the book was banned because of this. It happened two times.
Also, the reach of the book has been severely limited for whatever reasons. It is hardly getting any collection. Please show some support.
Consider this a request from my side.
