Saving Winter

Winter is my little sister. Our mom died a year ago and our father shortly after of a broken heart. I was hurt of course, but not nearly as bad as Winter, she went off the deep end. For a month after their deaths she cut off all her friends, cut me off, and was never home. All she did was party. Then one night she ran away. My mission is to find her. See...we are magic and our mother bonded us with a spell.. So we can sense when the other is in trouble..and I can sense that she is.
