Minerva McGonagall didn't mean to end up forty years in her own future. But here she is, and it's now her mission to make sure Harry Potter survives school. And to get Draco and Hermione together. And to make Umbridge's life hell. And hope that no one realises that Violetta Vernet, fourth part of the Trio, is actually their teenaged Transfiguration Professor. Very AU! From OttP
