standing still enough to be such a statue.
âFX,â Talis prompted.
Francis Xavier turned around and locked on to my eyes. âI will protect her.â
I was stunned by the slow certainty. It sounded as if he were saying wedding vows.
And then.
A flash. A blow to the eyes. Solid black shadows rushed out from everything, from Talis, from Francis Xavier, from the horses and the hillside, from every blade of grass. For an instant the sky was white and the world was flat and blackened.
Francis Xavier was moving. Before I even got a hand up to shield my eyes he was running forward, spreading his arms. He slammed into us, wrapping one arm around Talis and one around me, pushing us to the ground, sheltering us with his body.
For a moment I just huddled under Francis Xavier, stunned by the flash, by the blow. My eyes watered. The dry grass scratched my face. Like a chick under a wing, I was glad enough to be covered.
Not Talis, though. âGet off  . . .â He pushed his way free. âItâs miles away, honestly . . .â
Francis Xavier stood up.
There were spots in front of my eyes, and the night sky glowed a strange, sulfurous yellow.
âPlasma in the ionosphere,â said Talis. âAn orbital weapon.â
He squinted toward what seemed to be the source of itâbehind the horizon to the south and west. It looked as if the sun had mutated and was swelling back where it had set.
âIâve never seen one,â said Sri.
âI have,â I said. Talis had once stopped Elián from escaping with a bolt from the blue, scooped a small crater out almost at his feet. âButââ
âBut not like that,â said Talis. âThat was a city killer.â
âWhere . . . ?â breathed Sri.
Francis Xavier was counting under his breath. For a moment I thought he was trying to keep his temper, but then there was a distant crackle, not quite thunder. The sky made a sound like glass creaking. From the delay between light and sound, one could calculateââFour hundred miles,â said Francis Xavier. âCalgary?â
âWe donât have to guess,â said Sri.
Right. At least one of us could talk to the orbital weapons platforms.
âCalgary,â said Talis, like a one-word eulogy. He stood a moment, looking at the sick, false sunset. Then he clapped his hands together and twirled round to face us. âWell, kiddos. Something is obviously up, but no worries. Iâm sure Iâm on it.â
There was still, in the Red Mountains, a master copy of Talis. Someoneâsomething?âwho could access every networked sensor in the world, examine any database, command any satellite. Someone who was, apparently, âon it.â Our Talis might be able to talk to the weapons platform and confirm its firing strength and its target, but without the real-time access to information, he couldnât know the why of it.
âSo,â said Sri. âYou were saying, about the medium-sized cities?â
âIt might have nothing to do with Greta,â said Francis Xavier.
âYeah,â said Talis. âBut how likely is that, really?â
âWe should go,â said Francis Xavier. âIf there is a threat to you. Or to her. We should go. Our refuge is less than fifty miles.â
âNo,â said Talis.
âWe could use it as an extraction point. Or at least update the sitrep.â
âNo,â said Talis. âGreta is a novice. She canât ride fifty miles at a stretch. Not to mention I just pushed an ultrasound pulse through her prefrontal cortex. And itâs dark.â
âYou want us to stay here,â said Francis Xavier, obedient, soft-voiced, walking the knife edge between statement and question.
âWhat I want,â said Talis, âis for you to take first watch.â He was framed against the false sunset. Structures were developing in the charged sky as it
