Sunspot

The sunspot was huge. Nothing like it had ever been seen before---a twenty-billion square mile blot on the surface of the sun, and growing. Dr. Morris Tyler at Northern Arizona University in Flagstaff has a theory that might explain what's happening, and the news isn't good. Which is why he's under surveillance after having been told to keep his theory to himself. Keeping his theory under wraps isn't easy, not when a gorgeous reporter for Parsec magazine, Gail Dionne, has him in her sights, out to get a story. Tyler's well-ordered world spins out of control when all these forces converge on him, and the world begins to grow colder as the sun . . . goes . . . out.
