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.

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.
