A Sister's Fate

Trinity has been training since she was a young girl to fight a battle to keep her powers that she was born with. In her world, siblings are placed on an island with only their powers to keep them alive; however, you can only protect yourself- leaving your sibling alone. This was never a concern of Trinity's because she had no siblings, or so she thought. Now there is a sister that she has never met, that she must battle against; her skills and morals will be put to the test as she decides what's more important to her - her powers or her sister.
