—and then snatched away.

A blossoming in the blue. It started small: barely visible, a disruption in the sky, like a water droplet in an ink wash. It grew quickly and was joined by others.

The sky, it bled and bloomed. Pinwheels of color radiated out and out, horizon to horizon, joining and blending and merging like a kaleidoscope of stains. The sky… failed. It was beautiful to behold, and it was terrible. Terrible and terrible and terrible forever, amen.

This was how the world would end. Because of me. Because of me. Nothing worse has ever been done. In all of time, in all of space. I don’t deserve to live—

The sky would fail, and let them in. Them.Chasing, churning, devouring.

The Beasts are coming for you.

The Beasts.

Eliza fled from them, in the dream. She wheeled and fled, and her panic and guilt were as ravenous as the horror that was coming behind her. Somehow, it was her fault. Shewould do it. She would be the one to let them in.

Never. I will never—

“What the hell? Did you sleephere?”

Eliza gasped awake and there was Morgan before her, framed in the doorway, his hair a freshly shampooed flop down over his forehead, boy-band style. His pouty mouth was twisted with distaste. Dear god, only the dream could make Morgan Toth and his sneer seem benign by contrast. The way he was looking at her, you’d think he’d caught her in the middle of some lewd act, rather than dozing on a couch, fully dressed.

Eliza sat up straight. Her laptop screen had gone dark. How long had she been out? She clicked it closed, wiped her mouth with the back of her hand and was glad to find it droolless.

No drool and no screaming, but there was a pressure on her chest that she understood was a scream in the making. It would have burst out right here in the lab if Morgan hadn’t woken her, bless his horrid little self.

“What time is it?” she asked, standing up.

“I’m not your alarm clock,” he said, moving past her toward his preferred sequencer. There were two hulking DNA sequencers in the lab and Eliza had never been able to determine a difference between them, but she knew of Morgan’s preference for the one on the left and so, whenever possible, she tried to arrive first and claim it before he could. Of such petty victories is a day made sweet. Not today, though.

Given that it began with the dream and continued with exhaustion, that the world was falling apart, that her family had tracked her down and were out there, somewhere, andthat she was stuck in yesterday’s clothes, Eliza didn’t imagine the day held much in the way of sweetness.

She was wrong; it did. But it held a lot of other things, too, and was soon to veer wildly from any possible expectation she might have had of it.

Wildly.

It began a couple of hours later with a knock that made Eliza look up from her work. She’d been having a hard time concentrating anyway, data swimming before her eyes, and she was glad of the distraction. Dr. Chaudhary answered the door. He’d come in not long after Morgan and had kept his commentary on world events brief. “Strange days,” he’d said with a lift of his eyebrows before heading into his office. No chatterbox, Anuj Chaudhary. A tall Indian man in his fifties with a prominent hooked nose and thick hair turning silver at the temples, he had a genteel English accent and the manners of a Victorian gentleman.

“May I help you?” he asked the two men at the door.

One look at them, and Eliza felt transported into a TV show. Dark suits, regulation haircuts, bland features made even blander by a schooled lack of expression. Government agents. “Dr. Anuj Chaudhary?” asked the taller of the two, flipping out a badge. Dr. Chaudhary nodded. “We’d like you to come with us.”

“Just now?” Dr. Chaudhary asked, as calmly as if a colleague had popped in with an offer of tea.

“Yes.”

No explanation, and not a single extraneous word to soften the edges of their demand. Eliza wondered if government agents took a course in being cryptic. What was this about? Was Dr. Chaudhary in some kind of trouble? No. Of course not. When government agents came into laboratories and said, “We’d like you to come with us,” it was because they needed the scientist’s expertise.

And Dr. Chaudhary’s expertise was molecular phylogenetics. So the question was… what DNA did they want analyzed?

Eliza turned to Morgan and found him watching the exchange with creepy, blazing avidity. Alien invasion protocol, thought Eliza. As soon as he felt her eyes on him, he turned with a smirk and said, “Maybe I’m not the only non-idiot on the planet after all,” in a way that clearly singled herout as chief among idiots.

Which only made it incredibly sweet—here it was, her one taste of sweetness in a dark day soon to get much darker—when Dr. Chaudhary asked the agents, “May I bring an assistant?” and, getting a terse nod, turned… to her.

To her. Preciously, gloatingly sweet, almost too good to be true. “Eliza, if you wouldn’t mind accompanying me?”

From the sound Morgan made, Eliza could almost have believed that the air was expelled from his lungs by way of every orifice in his head, and not just his mouth and nose. His ears and eyes had to be in on it, too, cartoon-style. It was that fully committal, a scathing hiss of disbelief, injustice, scorn.

“But Dr. Chaudhary—” he began, but Dr. Chaudhary dismissed him, brusque and businesslike.

“Not now, Mr. Toth.”

And Eliza, sliding off her stool, paused just long enough to say, under her breath, “Suck it, Mr. Toth.”

“That’s what Ishould say to you,” he replied, acid and furious, sliding a narrowed-eyed glance of insinuation toward Dr. Chaudhary. Eliza froze, experiencing the weird sensation of her palm going white-hot and rigid with the urgency to slap him across the face. Mindful of the agents and her mentor watching, she mastered the urge, but her hand felt heavy with the unspent slap.

Well, it was some consolation to be the one gathering equipment at Dr. Chaudhary’s behest, and then the one following the agents out the door, leaving Morgan to expend his violent little-boy outrage alone.

There was a car waiting. Sleek, black, government. Eliza wondered what agency the men were with. She hadn’t been able to read their badges. FBI? CIA? NSA? Who had jurisdiction over… angels?

Dr. Chaudhary motioned Eliza into the car first, then slid in beside her. The door clicked closed, the agents climbed in front, and the car drew out into traffic. As the distance grew between herself and the museum, Eliza’s triumph faded, and worry began to overwhelm it. Wait, she thought, let’s think this through.

“Um, excuse me. Where are we going?” she asked.

“You’ll be briefed on arrival,” was the response from the front seat.

Okay.

Arrival where?

It had to be Rome.

Didn’t it?

Eliza flicked a glance to Dr. Chaudhary, who gave a minor shrug and lift of eyebrows. “This should be illuminating,” he said.

Illuminating?Would it be? Were they really going to get access to the Visitors?

She had a brief image of herself stepping up to do a cheek swab on one of them, and she felt the tug of hysteria. Who would have guessed, after all that she’d turned her back on, that sciencewould be bringing her face-to-face with angels? She had to swallow a laugh. Hey, Ma, look at me!God. It was only funny because it was so preposterous. She had chosen her own path, as different from her past as it could possibly be, and where did it lead her?

One of the biggest events in the history of humanity, and she would be there… sticking a Q-tip in an angel’s mouth? Open up.Another burble of hysteria, choked down and covered up with a throat-clearing. Eliza was going to analyze angel DNA. If they hadDNA. And they would, she thought. They had physical bodies; they had to be made up of something. But what would it look like? What resemblance would it bear to human DNA? She couldn’t begin to imagine, but she believed that it was how this mystery would be solved. At the molecular level.
