Time and Again

thirty. But he had no desire to be matched, mated or married yet. And when he did, Cal reminded himself it would be on his own ground. He would think of Libby only as a distraction, however pleasant, in a tense and delicate situation.
    He needed to be gone. He pressed his palms against the cool glass of the window as if it were a prison he could easily escape. This was an experience some men might have craved, but he preferred breaking the boundaries of his own world-and his own time.
    True, he'd learned things by reading the newspapers and watching the television. In the twentieth century the world was a long way from reaching peace, people worried a great deal about what to have for dinner and weapons were owned and used with reckless abandon. A dozen farm-fresh eggs could be had for about a dollar-which was the current U.S. currency-and everyone was on a diet.
    It was all very interesting, but he didn't think any of this information was going to help. He had to concentrate on taking his mind back to what had happened on board his ship.
    But he wanted to think about Libby, about what it had felt like to hold her against him. He wanted to remember how she had heated, about the way her lips had softened when his had met them.
    When her arms had come around him, he had trembled. That had never happened to him before. He had what he considered a normal, healthy track record with women. He enjoyed them, both for company and for mutual physical pleasure. Since he believed in giving as much as he took, most of his lovers had remained his friends. But none of them had ever made his system churn as it had during one kiss with Libby.
    All at once she'd taken him beyond what he knew and into some wild, gut-wrenching spin. Even now he could remember what it had felt like when her lips had gone hot and urgent against his. His balance had tilted. He'd almost believed he saw lights whirling behind his eyes. It had been like being pulled toward something of enormous, limitless force.
    His legs turned to water under him. Slowly he lifted a hand to brace himself against the wall. The dizziness passed, leaving a hollow throbbing at the base of his skull. And suddenly he remembered. He remembered the lights. The flashing, blinking lights in the cockpit. Navigational system failed. Shields inoperative. Automatic distress signal engaged.
    The void. He could see it, and even now the sweat pearled cold on his brow. A black hole, wide and dark and thirsty. It hadn't been on the charts. He would never have wandered so close if it had been on the charts. It had just been there, and his ship had been dragged toward it.
    He hadn't gone in. The fact that he was alive and undoubtedly on Earth made him certain of that. It was possible that he had somehow skimmed the edge of it, then shot like a rubber band through space and time. The scientists of his era would question that idea. Time travel was only a theory, and one that was usually laughed at.
    But he'd done it.
    Shaken, he sat on the edge of the bed. He'd survived what no one in recorded history had survived.
    Lifting his hands, he turned the palms upward and stared at them. He was whole, and relatively undamaged. And he was lost. He fought back a fresh wave of panic, balling his hands into fists. No, not lost-he wouldn't accept that. If he had been shot one way, it was only logical that he could be shot another. Back home.
    He had his mind, and his skill. He glanced at his wrist unit. He could work some basic computations on it. It wouldn't be enough, it wouldn't be nearly enough, but when he got back to his ship- If there was anything left of his ship.
    Refusing to consider the fact that it might be completely destroyed, he began to pace. It was possible that he could interface his mini with Libby's machine. He had to try.
    He could hear her downstairs. It sounded as though she were in the kitchen again, but he doubted she would fix him another meal. The regret came, too quickly to block, and the image of her sitting across the table from him flashed through his mind. He couldn't afford regrets, Cal reminded himself. And, if there was any choice, he wouldn't hurt her.
    He'd apologize again, he decided. In fact, if he was successful with her computer, he would get out of her life as smoothly and painlessly as possible.
    He moved quickly, quietly, into her room. He could only hope she would stay occupied until he made a few preliminary calculations. He'd have to be satisfied with those until
