Tom Riddle, top student of the prestigious Hogwarts School for Dance. Albus Dumbledore, searching for the hero in his famous end of year performance by holding open auditions. Harry Potter, attending said auditions only to listen to the live music for free. Severus Snape, dance instructor, tolerating nothing but perfection. The line between imagination and reality, a fickle thing.

Harry was trapped in a magical painting with no way out. His only company was the suspicious and curious stares of Tom Riddle. As Fate delivered this impossible crossing, an improbable and dangerous bond is made. Unconventional Time-Travel.

Seized by Voldemort at the end of his fifth year, in the Department of Mysteries, Harry was transformed into a cat and sent tumbling through time. Armed with nothing except teeth and claws, Harry has to handle the threat posed by Tom Riddle and his teenage followers. He intends to stop the genius young Dark Lord and sabotage him at every turn...in the form of a cat. Sounds simple?

Ten year old Harry Potter makes an insignificant decision that changes a lot of other insignificant things, which eventually changes very significant things. Because no matter what, Harry Potter never manages to do things by half measures. (AU from Hogwarts letter onwards, Diary!Tom, preslash/gen)
