She found a file named "letter.txt" buried in Documents, timestamped the day before she left. The letter was a draft she had never sent, written in the urgent, ragged hand of someone learning to be brave.

The words were not a map to return, but they were an address: a place where she had been whole and capable of rooms full of light.
