He tried to grab her. His hand passed through her body.

She smiled.

He tried to adjust to her level of displacement. He choked. Quickly he realized what was wrong; he rectified the air so he could breathe. She changed to normal just as he sprang. He hurtled through her as through the air itself.

She turned to face him. He was panting. "When I was a kid," she said, "I used to throw rocks when I got mad."

Damn you! His fists clenched. He towered over her.

She did not have any more time to waste with him. 'That means,' he had said, 'we're ready to invade.'

How much time did she have? The full extent of the menace was gradually taking form in her mind. With an army of indoctrinated mutants.... Invasion! Murder! Destruction! For an instant she wanted to collapse and cry like a frightened little girl.

What am I going to do? what am I going to do? what am I going to do? she thought frantically.

I've got to see someone! I've got to convince someone—I've got to show people my mutant powers: they'll have to believe me! The President, the Army....

How much time?
