When Su Li falls down a rabbit hole and out of the Veil, her whole life is turned upside-down. Not only has she appeared in the universe of Harry Potter, but she's also right at the beginning of the story... and she doesn't know how the story ends. But if she chooses to change the story, is it for the better, or for worse?

In another life, Harry made few choices. Here, he controls his own fate. Harry Potter's second year at Hogwarts involves a duelling club, an invisible man named Peter Pettigrew, an incompetent Defence teacher, and a deep suspicion that Albus Dumbledore might be a Dark Wizard. Smart!Harry. Independent!Harry. Neville as Harry's best friend. (sort of a self-insert, too)

There are always moments that can change a story dramatically, in small or large ways. Here, we choose the road not taken, the road less travelled... and that will make all the difference. Here, we follow the story of 'what might have been'. (Harry befriends someone in Diagon Alley and it changes his life. Neville-Harry friendship. Sort of a self-insert but not really?)

Loki falls. And breaks.

Harry and Snape meet up in death and discuss their regrets and their desires to have done better in life. Death overhears and gets annoyed - if they think they could do better then they might as well try. Only one problem now, Harry and Snape wake up having to live their new lives in each other's shoes - and seriously, they never thought life would be like this.
