The Trouble with Marriage Laws

When Hermione is matched by divination to both Harry AND Draco, her attempt to undo the decision reveals a long-hidden curse working against the pure-blood lines. She's determined to find a way to break the curse before the day she walks down the aisle, but the closer she gets to each of her fiances, the less certain she is that she wants a way out.
