A tragic accident kills Harry, & Draco is plagued by vivid memories of the same accident, which he was never believed to be in. A decade later, Hermione makes a shocking confession & an even more shocking proposition: firstly, she went back in time and saved Draco from the same accident, & secondly, if they go back in time together, they may be able to save both Draco & Harry.
