Now she walks through Blackwood Territory with power that makes Alphas kneel and a hunger that won't stop until she's taken everything they love. The quadruplets want her back. The bond is screaming to reconnect. But Lila didn't survive the rejection to fall into their arms again. She survived to watch them beg. And when four Alphas who've never begged for anything start crawling back to the mate they destroyed? That's when the real violence begins.

On her eighteenth birthday, Aria Veyne’s life is destroyed by a single burst of ancient magic. Kidnapped by powerful elders and taken to Ebonveil Academy, a school built to monitor the world’s most dangerous supernaturals, Aria quickly learns one terrifying truth. No one knows what she is. Not even her. But the moment her powers awakened, three heirs felt it. Archer Nightblade, the powerful werewolf heir, fights instincts that demand he protect her. Lucien Blackwell, the dangerously composed vampire heir, hides a hunger that has nothing to do with blood. Jasper Ashwyck, the charming fae heir, can’t decide if Aria is his greatest curiosity… or his greatest weakness. The closer Aria gets to them, the stronger her mysterious magic becomes. As secrets buried for centuries begin to surface, the elders realize they may have made a catastrophic mistake. Because Aria isn’t just another student. She may be the one person capable of changing the supernatural world forever. And if the darkness hunting her doesn’t claim her first, the girl with violet eyes just might.

I only wanted to survive senior year. Keep my head down, graduate, and leave Blackthorne Academy behind. But the moment I stepped through its iron gates, I became prey. The Academy is wrong in every way—no mirrors in the dorms, wolves howling during study hall, and strict orders to never leave your room on red moon nights. And then there are the four Alphas who have marked me with their eyes, their obsession, and their danger. Ronan Veyr, the storm-eyed heir destined for the crown, who recoils at my touch yet can’t seem to stay away. Cassian Drax, the golden boy trickster whose dangerous smile hides a ruthless streak. Malachai Frost, the untouchable prodigy who shadows me like a silent warden. And Professor Adrian Vale, the man who looks at me as if I’m a memory he can’t bury. They shouldn’t want me. I have no wolf, no pack, no power. But whispers of a legacy trail me through Blackthorne’s haunted corridors—a bloodline strong enough to crown kings… and dangerous enough to kill for. Strange visions tear through my body whenever one of them is near. My strength is rising, my secret unraveling, and I’m beginning to understand why my mother died to protect it. Because I am not wolf. I am something older. Something every Alpha was born to obey. And if I want to leave Blackthorne alive, I must decide: Will I let one of them claim me— or will I rise to command them all?

She was never meant to survive their world. Now she’s the only one who can burn it down. Lyra thought she was just a girl with strange dreams and a birthmark that shimmered beneath moonlight. But when a celestial event rips her from Earth and drops her into the brutal halls of the Academy of the Ascendant, she discovers a deadly truth: she’s the lost heir of a realm that erased her bloodline—and she’s carrying the forbidden magic that could unravel it all. The Academy is ruled by power and hierarchy. The weak are crushed. The strong ascend. And the Triad—three elite heirs born of elemental fire, storm, and air—will do anything to break her. Until they realize she’s more powerful than all of them. Mocked. Hunted. Desired. As Lyra unlocks the four elemental affinities no student should possess, she becomes the center of a prophecy that the Council has killed to keep buried. But it’s the fifth element—the forbidden Void—that marks her for something more. Survival means mastering her magic. Love could cost her everything. And rebellion might just start with a kiss. Perfect for fans of Zodiac Academy, Throne of Glass, and The Cruel Prince, Marked by Starlight is the explosive first book in a dark fantasy romance series filled with elemental magic, enemies-to-lovers heat, and a heroine who refuses to bow.

Ava is on the run for a crime punishable by death: killing a dragon. As a human-dragon hybrid, Ava has never doubted the godlike dragons’ dominance. Her life has been sheltered beneath their stained-glass wings in the city in the sky—until she murders one. Hunted, she flees to the human desert below the floating city. Yet she’s not alone.

Paired to be her master and she his caretaker, their friendship has always meant more than titles. The desert holds no sanctuary for them. The long-suffering ground dwellers are tired of having their water supply monopolized by the dragons above and want all dragon-kind dead—including Ava and Vito. Surrendering to the dragons isn’t an option with Vito by her side, and the rebellion has offered a tempting deal. They will keep Ava alive and hide her crime, but only if she reveals the weaknesses of dragon-kind and the secrets of her city. Ava must choose between her life and everything she once called home—including Vito, the closest thing to family she has left.
