The contents glittered like tiny shards of glass—or crushed hard candy.

Dmitri picked it up, angled it to the light.

It was, Illium saw, oddly beautiful, despite the fact that light revealed the crystals to have an undertone of sickly yellow.

“Chewed?”

He nodded at Dmitri’s question. “That seems to be the preferred method of ingestion with the users Trace was able to pinpoint. The supplier is taking extreme care to keep this underground and available to only a select clientele.”

“Exclusivity makes it more valuable.” Dmitri put the vial back down. “Effects?”

“Sexual high and addictive with a single hit.” Trace had reported seeing the woman from whom he’d seduced the sample quivering in carnal pleasure after she ate a sliver, her hands cupping her breasts and her eyes heavy lidded. “Long-term effects are unknown—Trace was able to confirm the drug only hit the streets two days past. We were lucky to pick up on it.”

“No. We weren’t lucky; we were prepared.” Dmitri had begun to create a network of informants throughout the city during the lead-up to the battle, and it was those informants who had reported a rising excitement in the wealthy vampire populace. All of it related to a mysterious new high.

Many of these new informants were human and a number were blood donors, specifically genetically blessed donors who came into contact with older, more powerful vampires on a regular basis. The trick was that none of the informants knew they served the Tower. One set of exclusive donors, for example, reported to the woman who ran the city’s top vampire club, in return for the cachet of being in her inner circle.

The idea of the subtle but powerful network had come from Raphael.

“Elena,” the archangel had said, “has made me realize we’re not fully utilizing all our assets.”

They’d been standing on the Tower roof at the time, the wind a savage beast. When Raphael turned to Dmitri, midnight black strands of hair had whipped across his face. “The mortals see things we do not, pay attention to those we might otherwise dismiss.” Facing the wind once again, Raphael had continued. “We need that information, but I will not drag Elena’s friends too deeply into the immortal world.” An instant of piercing eye contact. “Such can end only badly for them.”

Dmitri knew Raphael was no longer talking about Elena’s friends, but about the horror of Dmitri’s own past. “I do not blame you, sire. I never have.” He blamed the vicious angel who had tortured them both. “Without you, I would’ve carved out my heart and been lying dead in a distant grave an eon ago.”

“I blame myself, Dmitri, and I would not have Elena feel the same. Set up the network using mortals who have freely chosen to linger on the fringes of the immortal world as the base.”

“Raphael.” When the archangel turned to look at him with those eyes that burned with power, Dmitri had extended his arm. “The past is past, and if there ever was a debt between us, it was wiped clean the day you Made Honor.” Those vampires Made by an archangel were stronger from day one, harder to injure or kill. “You are my liege, but you will always first be my friend.”

Raphael’s hand had closed over his forearm, his over the archangel’s. “I hope to hear the same words a thousand years hence.”

“You will.” Both Dmitri and Raphael had come close to losing themselves to the insidious cold of eternity, but that was no longer a threat.

Today, it was Illium who concerned Dmitri. The majority of people, mortal and immortal, saw charm and a vivid zest for life when they looked at the blue-winged angel. Dmitri saw increasing power and an increasing darkness. All that held the darkness at bay was Illium’s tight-knit connection to Elena and Raphael, and to the Seven. But there would come a time when Illium became too much a power to remain in the city.

Then who would keep him . . . human?

“How long does the Umber high last?” Dmitri asked, making a mental note to speak to Raphael about Illium’s slow and near-imperceptible descent into the icy abyss that had nearly consumed the two of them. Unlike the others in the Seven, Illium couldn’t be seconded back to the Refuge to assist Galen and Venom; the distance from Elena and Aodhan, in particular, would indisputably hasten the ravages of the kind of power at Illium’s command.

“Longer than the high from a honey feed,” the blue-winged angel said in response to his question.

Dmitri frowned. A vampire’s metabolism differed from a mortal’s, meaning normal drugs, no matter how hard, metabolized too quickly to be worth the cost or the bother. A honey feed—drawing blood directly from the vein of a drug-addicted mortal who’d just shot up, snorted, or otherwise ingested their poison of choice, provided a trip that could last for up to ten minutes.

“How much better?”

“An hour per half gram of Umber.”

Dmitri went motionless. “An hour.” No other known drug on the planet had such an intense effect on the vampire population. “Unsurprising, then, that it’s become so coveted so quickly.”

“Trace has been able to pinpoint ten users so far, all gilded lilies.”

Dmitri knew the type: pretty but useless. Older, wealthy vampires who existed only to discover new indulgences, new sins. Anything to break the ennui. Dmitri had once, during the worst of his pain, joined them—only to discover he couldn’t spend his days doing nothing. It was a vapid, empty existence, and even as self-destructive as he’d been, he couldn’t sink into it. “They’re probably the only ones who can afford the drug.”
