To Love Again (гет)

Things go haywire when two rituals are performed at once. The Dark Lord was expecting to snuff out the only one who could defeat him before he or she could do so. Lily just wanted to prove to her friends that James is her soulmate. Now, her daughter from twenty years in the future was stuck in her timeline.
Harriet lost everyone. Or she thought she did. One minute, she was at her friends' and family's graves, the next she was face to face with her long dead mother. She was overwhelmed with grief, but she knew one thing, she was not going to let everyone die again.
Meanwhile, Severus was struggling to find his place in the world. If he could bring the one that the Dark Lord was looking for, surely he would be rewarded. He would finally fit in somewhere. The only problem is that he keeps having dreams of the future, an impossible future where Harriet was everything.
