He’d written back, You don’t tell them. You set boundaries if they cross a line, but you are their friend—and my mate. They will protect you on instinct. If you kick their asses out of the house, they’ll just sit on the roof.

I scribbled, You Illyrian males are insufferable.

Rhys had just said, Good thing we make up for it with impressive wingspans.

Even with him across the territory, my blood had heated, my toes curling. I’d barely been able to hold the pen long enough to write, I’m missing that impressive wingspan in my bed. Inside me.

He’d replied, Of course you are.

I’d hissed, jotting down, Prick.

I’d almost felt his laughter down the bond—our mating bond. Rhys wrote back, When I return, we’re going to that shop across the Sidra and you’re going to try on all those lacy little underthings for me.

I fell asleep thinking about it, wishing my hand was his, praying he’d finish at the Court of Nightmares and return to me soon. Spring was bursting all across the hills and peaks around Velaris. I wanted to sail over the yellow and purple blooms with him.

The next afternoon, Rhys was still gone, Amren was still buried in the book, Azriel off on a patrol of the city and nearby shoreline, and Cassian and I were—of all things—just finishing up an early afternoon performance of some ancient, revered Fae symphony. The amphi-theater was on the other side of the Sidra, and though he’d offered to fly me, I’d wanted to walk. Even if my muscles were barking in protest after his brutal lesson that morning.

The music had been lovely—strange, but lovely, written at a time, Cassian had told me, when humans had not even walked the earth. He found the music puzzling, off-kilter, but … I’d been entranced.

Walking back across one of the main bridges spanning the river, we remained in companionable silence. We’d dropped off more blood for Amren—who said thank you and get the hell out—and were now headed toward the Palace of Thread and Jewels, where I wanted to buy both of my sisters presents for helping us. Cassian had promised to send them down with the next scout dispatched to retrieve the latest report. I wondered if he’d send anything to Nesta while he was at it.

I paused at the center of the marble bridge, Cassian halting beside me as I peered down at the blue-green water idling past. I could feel the threads of the current far below, the strains of salt and fresh water twining together, the swaying weeds coating the mussel-flecked floor, the tickling of small, skittering creatures over rock and mud. Could Tarquin sense such things? Did he sleep in his island-palace on the sea and swim through the dreams of fishes?

Cassian braced his forearms on the broad stone railing, his red Siphons like living pools of flame.

I said, perhaps because I was a busybody who liked to stick my nose in other people’s affairs, “It meant a great deal to me—what you promised my sister the other day.”

Cassian shrugged, his wings rustling. “I’d do it for anyone.”

“It meant a lot to her, too.” Hazel eyes narrowed slightly. But I casually watched the river. “Nesta is different from most people,” I explained. “She comes across as rigid and vicious, but I think it’s a wall. A shield—like the ones Rhys has in his mind.”

“Against what?”

“Feeling. I think Nesta feels everything—sees too much; sees and feels it all. And she burns with it. Keeping that wall up helps from being overwhelmed, from caring too greatly.”

“She barely seems to care about anyone other than Elain.”

I met his stare, scanning that handsome, tan face. “She will never be like Mor,” I said. “She will never love freely and gift it to everyone who crosses her path. But the few she does care for … I think Nesta would shred the world apart for them. Shred herself apart for them. She and I have our … issues. But Elain … ” My mouth quirked to the side. “She will never forget, Cassian, that you offered to defend Elain. Defend her people. As long as she lives, she will remember that kindness.”

He straightened, rapping his knuckles against the smooth marble. “Why are you telling me this?”

“I just—thought you should know. For whenever you see her again and she pisses you off. Which I’m certain will happen. But know that deep down, she is grateful, and perhaps does not possess the ability to say so. Yet the feeling—the heart—is there.”

I paused, debating pushing him, but the river flowing beneath us shifted.

Not a physical shifting. But … a tremor in the current, in the bedrock, in the skittering things crawling on it. Like ink dropped in water.

Cassian instantly went on alert as I scanned the river, the banks on either side.

“What the hell is that?” he murmured. He tapped the Siphon on each hand with a finger.

I gaped as scaled black armor began unfolding and slithering up his wrists, his arms, replacing the tunic that had been there. Layer after layer, coating him like a second skin, flowing up to his shoulders. The additional Siphons appeared, and more armor spread across his neck, his shoulders, down his chest and waist. I blinked, and it had covered his legs—then his feet.

The sky was cloudless, the streets full of chatter and life.

Cassian kept scanning, a slow rotation over Velaris.

The river beneath me remained steady, but I could feel it roiling, as if trying to flee from— “From the sea,” I breathed. Cassian’s gaze shot straight ahead, to the river before us, to the towering cliffs in the distance that marked the raging waves where it met the ocean.

And there, on the horizon, a smear of black. Swift-moving—spreading wider as it grew closer.

“Tell me those are birds,” I said. My power flooded my veins, and I curled my fingers into fists, willing it to calm, to steady—

“There’s no Illyrian patrol that’s supposed to know about this place … ,” he said, as if it were an answer. His gaze cut to me. “We’re going back to the town house right now.”

The smear of black separated, fracturing into countless figures. Too big for birds. Far too big. I said, “You have to sound the alarm—”

But people were. Some were pointing, some were shouting.

Cassian reached for me, but I jumped back. Ice danced at my fingertips, wind howled in my blood. I’d pick them off one by one— “Get Azriel and Amren—”

They’d reached the sea cliffs. Countless, long-limbed flying creatures, some bearing soldiers in their arms … An invading host. “Cassian.”

But an Illyrian blade had appeared in Cassian’s hand, twin to the one across his back. A fighting knife now shone in the other. He held them both out to me. “Get back to the town house—right now.”

I most certainly would not go. If they were flying, I could use my power to my advantage: freeze their wings, burn them, break them. Even if there were so many, even if—

So fast, as if they were carried on a fell wind, the force reached the outer edges of the city. And unleashed arrows upon the shrieking people rushing for cover in the streets. I grabbed his outstretched weapons, the cool metal hilts hissing beneath my forge-hot palms.

Cassian lifted his hand into the air. Red light exploded from his Siphon, blasting up and away—forming a hard wall in the sky above the city, directly in the path of that oncoming force.
