Gen Salazar Slytherin & Godric Gryffindor

Awesome story with a different twist on the Salazar is Harry.  The story is hard to describe and lets just say no good deed goes unpunished. Salazar was trying to stop his descendant and thanks to polyjuice and the horcrux accidentally looses his memories and grows up as Harry Potter until he gets his letter. Then the memories come back and he turns the wizarding world upside down and inside out. He finds to his surprise in 2nd year he is not the only immortal. I have to say my favorite character is Nora Slytherin's snake. She is hilarious. The story is well thought out and paced appropriately. Salazar and Godric are not super-powered, they make mistakes, sometimes it comes back to bite them in the ass. Nobody is suddenly best friends. While the story is not finished it is over 400,000 and stops after 5th year. Definitely worth a read

Awesome story I love a good time travel story and this one is something else. How many people think "if only" in this case it's Loki. He answers a summons from Jane only to find that Thor is dead. He can't handle it especially since there is no one to blame. No one comes forward to take credit for his murder. No matter how hard he attacked Thor he was not supposed to die and the fact it was at another's hand is even worse. He finds a way but there is a heavy price, his life and future, in addition if anyone finds out it will all go back to the previous timeline. But he is no coward and his life has always revolved around Thor as if he was his sun without him there is no point. He goes back further then he thought and begins to try and ensure that Frigga and Thor survive. There are twists and turns as Loki is forced to take a hard look at his life. While there is some fairly emotional and angsty moments there is a lot of action and humor because fate loves laughing at people. Poor Loki. The author has a good handle on Loki’s character as well Odin. The flashbacks give the reader the basics of what happened and the more you learn the more you realize just how much Loki lost his mind.
