The sky flickered like a bad special effect from a time travel movie.

Away toward what the Church called the Top Pole, and which Brutha was coming to think of as the Hub, the sky flickered.

And beyond that another, and another-until all the sky flickered with alternating sheets of light and darkness.

Megan and Linus are sitting in the waiting area as the outside sky flickers hot and white.

Another peal of thunder racked the sky and a shard of lightning flickered to the west.

Everything blurred, and the yellow sky flickered.

The sky to the west was flickering with silent blue-white bursts of light.

And then the sky flickered, just once.

Outside, the sky was white with energy, flickering like a lightning bolt from Hell.

The sky above it flickered and danced, and the unseen rampart walls looked like a mountain ridge shadowed against a sunset.
