A short oneshot about how Severus Snape turned to the Light after hearing the prophecy. Follows canon and is quite interesting (I think.) This is a oneshot. K for implied ideas and mentions of violence.

Petunia Dursley has never existed. But the prophecy is still in place. Voldemort kills Lily and James, but the Killing Curse rebounds upon him. Dumbledore elects to send Harry to a new house every year. But this one decision will change the lives of so many... (AU. Pre-Hogwarts. First in the series. T cause it's Harry Potter.)
