Lovely death

My name is Jo.... My sisters name is ciera..... And we're shadowhunters people hunt demons and rouge down worlders, my parents died when I was 2 and I lived with my aunt trin and my uncle cris, ciera lived with other shadowhunters, so when I moved out of my aunt and uncles to move in with her I met some people..... Strange things have been happening.. I haven't seen ciera for two days and nobody knows were she is.
I'm ciera, the weirdest thing happened, I was just walking along on my way back to Jo, when everything went black, when I woke up... I was in a strange house........ With vampires!
I only own Jo and ciera everything else is not mine
