Undone

The building across from you only has 12 floors, so it doesn't block the light. The sun shines in at just the right angle to light things up without being blinding.

Everything gets a little bit darker, like a cloud has moved in front of the sun. This happens all the time, you just have to wait a few seconds for the cloud to pass.

But it doesn't pass. Puzzled, you move closer to the window and look up.

Something—your first instinct is space ship—is hovering above the street, blocking the sun.
