Third daughter of eve / harry potters sis

Hello my name is Jessica but I prefer JESS ! I am a mute but don't get me wrong I can talk and I would love to talk but ever since dad left for war I stopped ! My siblings gave up on trying to get me to talk months ago ! They don't care what happens to me they always say to me " why can't u be like Lucy or Edmund " or here is a good one " your the reason dad left us ! Your the reason are dad could die and you don't care!" That's the one that gets me but the only person who understands me is Edmund ! We share a room in the attic ! Well this is all I am telling you ! Bye
