In a world where ancient treaties keep monsters in check, Lyra Hale has spent her life hiding what she is. A human witch born of a forbidden bloodline, Lyra’s magic first awakened in childhood, wild, powerful, and dangerous enough to draw the attention of forces her mother spent years running from. When her mother vanishes without a trace, Lyra follows the only clue left behind to Transylvania, a land ruled by vampires and werewolves haunted by the aftermath of forbidden magic. Her arrival does not go unnoticed. Once human, once powerless, Caspian has built his reign on control and fear of vulnerability. Lyra’s magic, ancient, untamed, and resistant to domination, becomes both his greatest threat and his darkest obsession. As witches, vampires, and werewolves close in, Lyra is pulled into a hidden war between covens, courts, and prophecies long buried. Ancient elders awaken, feral creatures stalk the shadows, and whispers of a forbidden creation resurface, proof of what happens when love and power cross sacred lines. Bound to Caspian by dangerous magic neither fully understands, Lyra must choose whether to submit to the laws that seek to control her… or defy them and risk destroying the fragile balance holding the supernatural world together. Because in a realm built on blood and fear, purity is a provocation, love is rebellion, and some bonds were never meant to exist, yet refuse to be broken.

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.
