One overheard prophecy is enough to make Severus Snape betray the future he was meant to serve—but it is not fear of Voldemort that changes his life, it is the discovery that *you* are the centre of it. When Severus learns that a future child tied to your blood will one day bring about the Dark Lord’s downfall, you are immediately marked as a target, forcing him into a desperate bargain with Dumbledore to become a spy years earlier than he ever intended, all so he can stay close enough to keep you alive—even as he slowly realizes he may have already fallen in love with you too deeply to ever let you go.
