Harry is the Boy-Who-Lived, but he has a younger twin brother. This is an alternate first year, starting with Harry and Draco's meeting at Madam Malkin's. This time their conversation is a lot friendlier. Slytherin!Harry, no pairings.
This is the story of Vernon Dursley and Petunia Evans; how they first met and eventually fell in love. They are not the horrible adults the books describe, but just your average couple. PS/SS takes off where this story ends. One-shot.
