"What do you want to know?" he asked.
"I don't," she said, and wiped trickles of tears from her face. "I don't want to know anything anymore. I think I'm going crazy."
"Well, it's always a possibility." He shrugged. "Ada is a living mind inside an artificial form. A brilliant woman - a former assistant of mine, actually. This preserved the best parts of her. I have never regretted taking the steps to integrate technology and humanity."
"Well, of course you wouldn't. I have," Ada said, from nowhere in particular. Claire shuddered. There was something not quite right about that voice, as if it was coming out of some old, cheap AM radio speakers that had been blown out a few times. "Tell your new friend the truth, Myrnin. It's the least you can do."
He closed his eyes. "Ada was dying because I had a lapse."
"In other words," the computer said acidly, "he killed me. And then he trapped me inside this box. Forever. The fact that he doesn't regret it only proves how far from human he is."
"You are not trapped in the box forever," Myrnin said, "as you well know. But I still need you, so you will simply have to stop your endless wailing and get on with things. If you want an escape, research your way out."
"Or you'll what?"
Myrnin's eyes snapped open, and he bared his fangs - not that he could bite the computer. It was just a reaction of frustration, Claire thought. "Or I'll disconnect your puzzle sets," he said, "and you can read the works of Bulwer-Lytton for entertainment for the next twenty years before I take pity on you."
Ada was notably silent in response to that, and Myrnin folded up his fangs and smiled. "Now," he said to Claire, "let me explain Ada. She is the life force that powers the town, of course; without her, we could not operate the portals, and we could not maintain the invisible fields that ensure Morganville residents stay put, and suffer memory loss if they manage to make their way out of town. The drawback is that Ada is a living being, and living beings have . . . moods. Feelings. She has been known to grow fond of people, and to sometimes interfere. Such as with your friend Michael."
"Michael?" Claire blinked, intrigued despite everything. She didn't want to know more. . . . Oh, hell, yes she did. She really did. "What do you mean?"
"I mean that Ada interceded to keep Michael alive, because she could. Ada's presence is most felt in the Founder Houses, which are closely linked to her; she can, with enough of an effort, manifest in them, or anywhere there is a portal, for short periods of time. In Michael's case, she chose to save his life by storing him in the matrix of the Glass House rather than allowing him to die when Oliver attempted, and failed, to turn him into a vampire."
"She didn't just save him, she saved him," Claire said. "Like a computer saving a crashed file."
"I suppose, if you want to put it in mundane terms." Myrnin yawned. "I told her to let him go. She ignored me. She does that."
"Frequently," Ada's disembodied voice said. "And with great satisfaction. So. You are the girl from the Glass House. Myrnin's new pet."
"I . . ." Claire wasn't sure how to respond to that, so she settled for a quick shrug. "I guess."
"You've done well," Ada said. "You work the portals without much understanding of how they function or how to create them, but I suppose that most modern children couldn't begin to construct the toys with which they play."
Claire's cell phone suddenly rang, its cheerful electronic tone startling in the silence. She jumped, flailed, and fished it out of her pocket, only to have it immediately go dark.
"Did you do that?" she asked.
"Do what?" Ada asked, but there was a dark, amused edge to the words. "Oh, do forgive. I've got little enough to occupy me down here in the dungeon. In my box."
"Ada." Myrnin sighed. "I brought her here so you could explain to her how to maintain your functions, not to have her listen to your endlessly inventive complaints."
Ada said nothing. Nothing at all. In the silence, Claire heard the steady whir and click of gears turning, and the hiss of steam - but Ada stayed quiet.
"She's pouting," Myrnin said, and heaved himself up to a sitting position. "Don't worry, my dear. You can trust Claire. Here, let me introduce you properly."
Myrnin's idea of a proper introduction was to grab Claire by the arm and haul her over in front of the machine. Before she could yell at him to let go, he slipped back a metal cover and pushed her hand down on a metal plate . . . and something pierced her palm, lightning fast, like a snakebite. Claire tried to snatch her hand back, but something - some force - held it in place.
She could feel blood trickling out of the hot, aching wound. "Let go!" she yelled, and kicked the machine in fury. "Hey! Hey!"
Ada giggled. It was a weirdly metallic sound; up close, she really didn't sound human at all, more like parts grinding together inside.
The force holding Claire's hand in place suddenly let go, and she stumbled back, clutching her burning hand to her chest and trying - without much success - to stop herself from gasping for breath. She was afraid to look, but she forced herself to open her left hand.
There was a small puncture wound in the middle of her palm, a red circle about the size of a pencil point; there was a whiter circle all around it, like a target. As Claire watched, the white faded.
Blood trickled out of the hole in her skin in fat red drops. Claire looked at Myrnin, who was standing a few feet away; he was gazing at her hand with fascination.
Ewwwwww.
Claire made a fist, willing the bleeding to stop. "What the hell was that?"
"That?" Myrnin didn't seem to be able to take his gaze off of her fist. "Oh, it's simple enough. Ada needed to know who you were. She'll know you now, and she'll follow your orders."
Ada made a sound suspiciously like a strangled cough.
"That doesn't explain why she bit me!" Claire said.
Myrnin blinked. "Blood is the fuel that drives the engine, my dear. As with us all. Ada requires regular infusions of blood to operate."
"You never heard of plugging her in? My God, Myrnin, you made a vampire computer?"
"I . . ." He seemed honestly unsure how to answer that, and finally gave up. "She requires about a pint of blood each month - not refrigerated blood; it should be warmed to at least room temperature, preferably to body temperature, of course. I generally feed her close to the beginning of the month, though she can, in a pinch, go weeks without nourishment. Oh, and do feed her at night. Blood is less effective when offered under the influence of the sun. We do work according to hermetic rules here, you know."
"You're insane," Claire said. She backed up against a wall and stood there staring at him. "Seriously. Insane."
He didn't pay any attention to her at all. "You also need to recalibrate her once on each solstice day, winter and summer, to accommodate the shifting influences of sun and moon. You do remember the hermetic symbology I taught you, don't you? Well, the formula is quite simple. I've noted it down for you, here." Myrnin patted his jacket pockets, and finally came up with a much-scratched-out, torn scrap of grimy paper, which he offered to Claire.
She didn't take it. "This is crazy," she said again, as if it was really important that he understand it. Myrnin slowly raised his eyebrows. "You built a vampire computer. Out of wood. And glass. You're not . . . This isn't . . ."
He patted her gently on the shoulder. "This is Morganville, dear Claire. You should know by now that it would not be what you expect." With a sudden burst of energy, Myrnin took Claire's unwilling hand, slapped the paper into it, and bounced to his feet. "Ada!"
"What?" The computer sounded surly. Hurt. She's not even real, Claire told herself. Yeah. She's not real, and she drinks blood. She just drank mine.
"You will accept all commands from Claire Danvers as my own. Do you understand me?"
"All too clearly." Ada sighed. "Very well. I shall record her essence for future reference."
Myrnin turned back to Claire and folded her hand over the scrap of paper. His fingernails were filthy and sharp, and she shuddered at how cold his touch was. "Please," he said. "You must keep this safe. It's the only record of the sequence. I made it to remind myself, in case . . . when I forgot. If you get the sequence wrong, you could risk killing her. Or worse."
