Save Yourself

During the summer after Harry's fifth year he decides he had enough. As soon as school starts he would escape from his "friends" and leave. If he could get his hands on a time turner then he would do a lot more than leave. He would go back and save Sirius again or maybe he'd be able to go back far enough to save himself. With a little help from some slytherins and a certain house elf Harry gets his hands on an experimental time turner, who knows where it will take him.
