As Time Goes By
by Tanith Lee
The narrator tells of a time travel paradox where a girl of fifteen meets Day Curtis who
has come from a disaster that’s still another sixteen years in the future—and she
returns to the scene years later to warn him.
Let me prompt you. You’re dead, Curtis. Or you will be.
