Voldemort chooses Neville but the Potters do not escape unscathed. Five years later, Lily Potter walks back into Severus Snape's life. Things are about to get complicated. AU.

His life had been a mockery to itself, as too his death it seemed. For what kind of twisted humour would force Severus Snape to relive his greatest regret? To return him to the point in his life when the only person that ever mattered in his life had already turned away.

Severus Snape is trapped. Trapped between his father, his mother, and his House, being driven into the Dark. Until Sixth Year, when all his secrets are revealed, to the people he least wanted to discover them. Enemies become friends, relationships are remade...and changes occur that could affect the fate of the entire Wizarding World.

Snape has the opportunity to go back in time and fix the mistakes he made. The question is, will he make the right decisions this time around?

Sometimes all that's needed for enormous differences is a small change, as small as the order of a few sentences in a heated row. Lily Evans unconsciously makes one such change while arguing with her best friend, and the magnitude of consequences her actions cause holds the potential to reshape not only herself and the people around her, but their world's very future. A What-if AU

19-year-old Lily Evans finds herself mysteriously in the future, a world she no longer recognizes. With no one else to turn to, she goes to her old friend Severus for help and sets out to fix the past. What will Severus do when the love of his life returns to him? [SS/LE]

A oneshot I just had to get out. I've secretly always been a fan of Sev/Lily and this particular plot just popped into my head! Severus just has to convince Lily how sorry he is for what he called her. Can he do it?
