The Seventh Life

If Draco had looked the other way, he may never have seen him again. But Draco turned, because he always would have turned. He found him, because he always would have found him - in life, in death, or in Paris.
OR:
Draco is an immortal vampire. Harry is trapped in eternal cycles of life, death, and reincarnation. They meet again in Paris, and the seventh life isn't any less complicated than the first.
