Clockwork Princess

trying to decide what to name them. Will had been the one to suggest their names: Balios and Xanthos, after the immortal horses of Achilles.
We two can fly as swiftly as Zephyrus, who they say is the fleetest of all winds
.
    But those horses had been immortal, and Balios was not. Stronger than an ordinary horse, and faster, but every creature had its limits. Will lay down, his head spinning, and stared up at the sky—like a gray sheet pulled tight, touched here and there with streaks of black cloud.
    He had thought, once, in the brief moments between the lifting of the “curse” and the knowledge that Jem and Tessa were engaged, of bringing Tessa here to Wales, to show her the places he had been as a child. He had thought to take her down to Pembrokeshire, to walk around Saint David’s Head and see the cliff-top flowers there, to see the blue sea from Tenby and find seashells at the tide lines. These all seemed the distant fancies of a child now. There was only the road ahead, more riding and more exhaustion, and probable death at the end of it.
    With another reassuring pat on his horse’s neck, Will heaved himself to his knees and then his feet. Fighting dizziness, he limped to the crest of the hill, and looked down.
    A small valley lay below him, and within it was cradled a diminutive stone village, little bigger than a hamlet. He took his stele from his belt and wearily carved a Vision rune into his left wrist. It lent him enough power to see that the village had a square, and a small church. It would almost certainly have some sort of public house where he could rest for the night.
    Everything in his heart screamed to go on, to
finish this—
he could not be more than twenty miles from his goal—but to go on would be to kill his horse and, he knew, to arrive at Cadair Idris himself in no fit state to do battle with anyone. He turned back toward Balios and with a measured application of coaxing and handfuls of oats managed to get the horse to its feet. Gathering the reins in his hand and squinting into the sunset, he began to lead Balios down the hill toward the village.
    The chair Tessa sat in had a high, carved wooden back, hammered through with massive nails, the dull ends of which poked into her back. In front of her was a wide desk, weighed down by books on one end. Before her on the desk was a clean tablet of paper, a jar of ink, and a quill. Beside the paper sat John Shade’s pocket watch.
    On either side of her stood two massive automatons. Little effort had been expended to make them resemble humans. Each was nearly triangular, with thick arms protruding from either side of their bodies, each arm ending in a razor-sharp blade. They were frightening enough, but Tessa could not help but feel that if Will were there, he would have commented that they looked like turnips, and perhaps made up a song about it.
    “Take up the watch,” said Mortmain. “And Change.”
    He sat across from her, in a chair much like hers, with the same high curving back. They were in another cave room, which she had been led to by automatons; the only light in the room came from an enormous fireplace, large enough to roast an entire cow in. Mortmain’s face was cast into shadows, his fingers steepled below his chin.
    Tessa lifted the watch. It felt heavy and cool in her hands. She closed her eyes.
    She had only Mortmain’s word that he had sent the
yin fen
, and yet she believed him. He had no reason not to do it, after all. What difference did it make to him whether Jem Carstairs lived a little longer? It had only ever been a bargaining tool to get her into his hands, and here she was,
yin fen
or not.
    She heard Mortmain’s breath hiss out between his teeth, and she tightened her fingers’ grip on the watch. It seemed to throb suddenly in her grasp, the way the clockwork angel sometimes did, as if it had its own life within it. She felt her hand jerk, and then suddenly the Change was on her—without her having to will it or reach for it as she usually did. She gave a little gasp as she felt the Change take her like a harsh wind, pushing her down and under. John Shade was suddenly all around her, his presence enveloping hers. Pain drove up her arm, and she let go of the watch. It thumped to the desk, but the Change was unstoppable. Her shoulders broadened under the dressing gown, her fingers turning green, the color spreading up her body like verdigris over copper.
    Her head jerked upright. She felt heavy, as if an
