“Duck,” called Camilla.
Camilla had somehow propped herself on the arm with the mangled shoulder wound, which was in no condition for propping. Her good arm was up behind her head, holding the blade of her knife. Gideon ducked. The knife whistled over the top of Gideon’s head in a flashing blur and buried itself in Cytherea’s upper back.
This time Cytherea screamed. She went stumbling away from Ianthe’s prone form, and Gideon saw what Camilla had been aiming at: a lump, a delicate swollen mass, right next to Cytherea’s shoulder blade. It bulged out only slightly, but once you saw it, it was impossible to unsee—especially with a long knife buried squarely in its centre. Cytherea fumbled one hand over her shoulder, bone appendage drifting into dust, groping for the knife. She found it—she pulled it out, drawing a spurt of appalling black-and-yellow liquid from the wound.
The Lyctor turned her head and coughed miserably into the crook of her elbow. Then she looked at the knife, wondering at it. She turned her head to look at Camilla and Harrow and Gideon. She sighed pensively and ran one hand through her curls again.
“Oh no,” she said, “heroics.”
She dropped the knife, fell gracefully to one knee beside Ianthe, and lifted a limp arm—the one that was still connected to her body—in a cruel mockery of hand holding. Gideon thought for a bad second she was going to pull the limb clean off, and wondered how far she could throw a longsword—except no, her longsword was never going to leave her hands again, thank you—but Cytherea was just siphoning. There was the deep-gut lurch as energy drained from the younger Lyctor to the older, knitting the gross knife wound back up again.
“An inadequate Lyctor,” said Cytherea, as though giving Gideon and Camilla a hot tip on stain removal, “still makes a perfect power source … an everlasting battery.”
She stood back up and wiped her mouth with the back of her hand. Then she began walking toward Gideon: calm, almost insolent in her lack of aggression. This was somehow much scarier than if she’d stalked forward with a hateful glare and a rill of mad laughter.
Gideon planted herself before Camilla and the unconscious body of her adept and held her sword aloft. They were alone in a back area of the courtyard: a little area not yet buried in rubble or tilled up by the titanic fight between two immortal sorcerers. Dead trees bowed overhead. Gideon stood behind the iron fence that had once protected some herbaceous border, as though its bent, bowed spikes would be good for anything other than throwing herself down on as one last fuck-you salute.
Camilla was huddled in a corner, now standing upright—that was probably her own last fuck-you salute—but her wounded arm hung uselessly. She had lost a lot of blood. Her face was now pallid olive.
“Ninth,” said the Sixth impatiently. “Get out of here. Take your necromancer. Go.”
“Hell no,” said Gideon. “It’s time for round two.” She considered that. “Wait. Is this round three now? I keep losing count.”
Cytherea the First was brushing bloodstains off her makeshift dress, the blood leeching into her fingers as though it obeyed the merest touch of her fingertips. She vaulted daintily into their part of the courtyard and smiled Dulcinea’s smile at Gideon: dimpling, bright-eyed, as though they both knew something extra nice that nobody else did.
“There’s that two-hander,” she said admiringly.
“Want a closer look?” said Gideon.
The Lyctor arched her free hand languorously behind her back; she slid into position, weighting herself on her back foot, the sword in her hand luminous—tinted green like still water, or pearls. “You know you can’t do this, Gideon of the Ninth,” she said. “You’re very brave—a bit like another Gideon I used to know. But you’re prettier in the eyes.”
“I may be from the Ninth House,” said Gideon, “but if you say any more cryptic shit at me, you’re going to see how well you can regenerate when you’re in eighteen pieces.”
“Cry mercy,” said Cytherea. The dimple was still there. “Please. You don’t even know what you are to me … You’re not going to die here, Gideon. And if you ask me to let you live you might not have to die at all. I’ve spared you before.”
Something ignited deep in her rib cage.
“Jeannemary Chatur didn’t ask for mercy. Magnus didn’t ask for mercy. Or Isaac. Or Abigail. I bet you Palamedes never even considered asking for mercy.”
“Of course he didn’t,” said the Lyctor. “He was too busy detonating.”
