Killing the Heir of Slytherin

This isn't a story where a pretty girl saves a misunderstood boy whilst slowly falling in love. Gabrielle Vermo has a plan, one that not even the dark-lord-to-be could stop. Time means nothing when all you have left is anger for the one who took everything. There has never been a thinner line between love and hate, and the two people who can't work out which side they are on.
