Dark Lightning

Author John Varley returns to his Thunder and Lightning series with a novel of how one man's volatile genius could alter a starship's epic plunge into a future where human survival is just a theory...

On a voyage to New Earth, the starship Rolling Thunder is powered by an energy no one understands, except for its eccentric inventor Jubal Broussard. Like many of the ship's inhabitants, Jubal rests in a state of suspended animation for years at a time, asleep yet never aging.

The moments when Jubal emerges from suspended animation are usually a cause for celebration for his family, including his twin daughters-Cassie and Polly-and their uncle who is captain of the Rolling Thunder. But this time, Jubal makes a shocking announcement...

The ship must stop, or everyone will die.

These words from the mission's founder, the man responsible for the very existence of the Rolling Thunder, will send shock waves throughout the starship-and divide its passengers into those who believe and those who doubt. And it will be up to Cassie and Polly to stop a mutiny, discover the truth, and usher the ship into a new age of exploration...
