Time and love don't mix

Cassia Potter, Harry Potters older sister went on the run with the golden Trio, but when they went to Godric's Hollow on Christmas eve, something went horribly wrong in Bathilda Bagshot's house and Cassia found herself on Albus Dumbledore's desk, with him sitting behind it.
Suddenly, Sirius' and Remus' strange behaviour in her presence makes sense, when she meets them in Hogwars as eighteen and seventeen year olds.
By now, she expects the most horrible to happen: meeting her parents, knowing they would die in only four years and not being able to do anything about it, because things could get much, much worse.
But then something unexpected happens and Cassia has to deal with the aftermath, feeling as alone as ever.
