Sister Phantomhive

This takes place after Ciel met Alois, also the events that took place in Book of Circus have also happened. I will be changing the plot a bit, like who dies and does not die because I will be adding an original character. So if you like fanfics that follow the story line this isn't for you.

When Lily finally escapes the years of confinement she endured, she finds Ciel who is suprised with the news that Lily is infact his older sister that was stolen from her parents as an infant. Ciel was never told this for his parents were too heart broken to ever mention it. What will happen when the two siblings encounter many arguments that don't die down easily? And what rash decisions will come if it.
