Harry Potter and the Legacy of the Immortal

It always starts with a letter. One parchment, sealed in a crisp envelope, addressed to one person and one person only.

It's almost been a year and a half since Harry and Ginny watched their youngest son board the Hogwarts Express for the first time, heading towards the most difficult challenge of his life. Hogwarts was not what Albus had expected, but he continued to thrive and fight to avoid being the laughingstock of the school, with no help from his malicious brother. All of the trio's family lives had been hectic since the war, as they always had.

When it all calms down, a strange peace settles on the large, extended family. Like before, all is well. That is, until one night...one decision. Suddenly, the Potters and Granger-Weasleys, along with an old schoolmate, are fighting for their lives while trying to keep hidden in the walls of Hogwarts, their safe-haven that had once protected them. With more than just their own lives to worry about, Harry, Ron, Hermione, along with others that have been roped into the battle, shelter the reachable children the best way they can. But will it be enough? Can they protect their families and stop the other side once and for all? Who will make it out alive?

Hello everyone! This is my first fanfiction book, so I hope you all like it! I will update as much as I can, and the time between chapters may vary, but it will never be longer than a week. My lack of life during quarantine allows me a lot of time to write. Harry Potter has always been my favorite book and movie series. JK Rowling has a powerful way with words and I could never become tired of her writing. This story will never be as good as the actual series, but I hope you all like it nonetheless. Also, this is a sequel to the main seven books, not the Cursed Child. It is a bit like an alternate ending.
