Mistborn #02 The Well of Ascension

counterparts, showing Vin exactly what would happen a few moments in the future.
    Only the Mistborn was immune. Rather than shooting out a single atium shadow, he released dozens—the sign that he was burning atium. He paused just briefly. Vin's own body would have just exploded with dozens of confusing atium shadows. Now that she could see the future, she could see what he was going to do. That, in turn, changed what she was going to do. That changed what he was going to do. And so, like the reflections in two mirrors facing each other, the possibilities continued into infinity. Neither had an advantage.
    Though their Mistborn paused, the four unfortunate Thugs continued to charge, having no way to know that Vin burned atium. Vin turned, standing beside the body of the fallen Smoker. With one foot, she kicked the soundsticks into the air.
    A Thug arrived, swinging. His diaphanous atium shadow of a staff blow passed through her body. Vin twisted, ducking to the side, and could feel the real staff pass over her ear. The maneuver seemed easy within the aura of atium.
    She snatched one of the soundsticks from the air, then slammed it up into the Thug's neck. She spun, catching the other soundstick, then twisted back and cracked it against the man's skull. He fell forward, groaning, and Vin spun again, easily dodging between two more staves.
    She smashed the noise sticks against the sides of a second Thug's head. They shattered—ringing with a hollow sound like that of a musician's beat—as the Thug's skull cracked.
    He fell, and did not move again. Vin kicked his staff into the air, then dropped the broken soundsticks and caught it. She spun, twisting the staff and tripping both remaining Thugs at once. In a fluid motion, she delivered two swift—yet powerful—blows to their faces.
    She fell to a crouch as the men died, holding the staff in one hand, her other hand resting against the mist-wetted cobbles. The Mistborn held back, and she could see uncertainty in his eyes. Power didn't necessarily mean competence, and his two best advantages—surprise and atium—had been negated.
    He turned, Pulling a group of coins up off the ground, then shot them. Not toward Vin—but toward OreSeur, who still stood in the mouth of an alleyway. The Mistborn obviously hoped that Vin's concern for her servant would draw her attention away, perhaps letting him escape.
    He was wrong.
    Vin ignored the coins, dashing forward. Even as OreSeur cried out in pain—a dozen coins piercing his skin—Vin threw her staff at the Mistborn's head. Once it left her fingers, however, its atium shadow became firm and singular.
    The Mistborn assassin ducked, dodging perfectly. The move distracted him long enough for her to close the distance, however. She needed to attack quickly; the atium bead she'd swallowed had been small. It would burn out quickly. And, once it was gone, she'd be exposed. Her opponent would have total power over her. He—
    Her terrified opponent raised his dagger. At that moment, his atium ran out.
    Vin's predatory instincts reacted instantly, and she swung a fist. He raised an arm to block her blow, but she saw it coming, and she changed the direction of her attack. The blow took him square in the face. Then, with deft fingers, she snatched his glass dagger before it could fall and shatter. She stood and swung it through her opponent's neck.
    He fell quietly.
    Vin stood, breathing heavily, the group of assassins dead around her. For just a moment, she felt overwhelming power. With atium, she was invincible. She could dodge any blow, kill any enemy.
    Her atium ran out.
    Suddenly, everything seemed to grow dull. The pain in her side returned to her mind, and she coughed, groaning. She'd have bruises—large ones. Perhaps some cracked ribs.
    But she'd won again. Barely. What would happen when she failed? When she didn't watch carefully enough, or fight skillfully enough?
    Elend would die.
    Vin sighed, and looked up. He was still there, watching her from atop a roof. Despite a half-dozen chases spread across several months, she'd never managed to catch him. Someday she would corner him in the night.
    But not today. She didn't have the energy. In fact, a part of her worried that he'd strike her down. But . . .she thought. He saved me. I would have died if I'd gotten too close to that hidden Mistborn. An instant of him burning atium with me unaware, and I'd have found his daggers in my chest .
    The Watcher stood for a few more
