Petunia married a biochemist, and Harry grew up reading science and science fiction. Then came the Hogwarts letter, and a world of intriguing new possibilities to exploit. And new friends, like Hermione Granger, and Professor McGonagall, and Professor Quirrell... COMPLETE.

Hermione overhears something she shouldn't concerning Professor Snape and decides that maybe the House-elves aren't the only ones in need of protection.

We have the testimony of Harry, but witnesses can be notoriously unreliable, especially when they have only part of the story. This is a biography of Severus Snape from his birth until his death. It is canon-compatible, and it is Snape's point of view.

Hermione quite literally crashes her way back through time by roughly twenty years. There is no going back; the only way is to go forward. And when one unwittingly interferes with time, what one expects may not be what time finds...

The war is over. Hermione Granger's life, while safer, is no less complicated. Victory has had unintended consequences which affect not only Hermione, but all those around her.

Hermione cannot remember, and Severus cannot forget. Epilogue has been added, and the tale is now complete.
