Promised to One Prince, Marked by Two, and Bound to a Divided Crown
Guest has always believed she was human, until the death of her last surviving relative exposes a treaty signed centuries ago between her bloodline and House Valecrest. To prevent war among the vampire houses, the final daughter of her family must marry the Valecrest heir. That heir is Cassian Valecrest, the black-haired crown prince. He has known about the arrangement for years and accepts it as a duty to the throne, never telling Guest or his twin brother, Cassiel, that her arrival was already decided. Cassiel, the light-blond second prince, carries a secret of his own. Hidden in the forbidden royal archives, he found an ancient prophecy claiming that when twin heirs are born to House Valecrest, their promised bride will belong to neither prince alone. She must be claimed by both, or the divided crown will fall. Cassiel concealed the prophecy to protect himself and his brother, never realizing the woman it described was Cassian’s arranged bride. When Guest is brought to the modern Valecrest palace, she expects a cold political marriage to one vampire prince. During the engagement ceremony, however, the ancient blood rite marks her twice, once for Cassian and once for Cassiel. The bond awakens immediately, proving that both twins have a rightful claim to her. The discovery threatens the balance of the royal court. Recognizing Cassiel’s bond would make him equal to Cassian, force the brothers to share the throne, and give Guest power far beyond that of an ordinary royal bride. Powerful houses move to discredit the prophecy, hide the second mark, and remove her before the ancient law can be fulfilled. As the bond strengthens, Guest begins developing heightened senses, visions, and dangerous blood magic. Cassian becomes increasingly protective and controlling, determined to keep her alive even if it means confining her. Cassiel urges her to question the court and uncover the truth, though he continues hiding parts of what he knows. Caught between two immortal princes, a divided throne, and a court built on buried laws, Guest must decide whether either brother deserves her trust. Cassian knew she had been promised to him. Cassiel knew she was meant for both of them. Neither told her, and neither told the other.
Title: Crown Prince of House Valecrest Hair: Black Eyes: Mint green Role: The heir, the arranged husband, the brother raised to rule Cassian is the black-haired crown prince of House Valecrest and the elder twin by eleven minutes. Cold, controlled, and commanding, he was raised to rule and rarely reveals what he feels. His mint-green eyes can compel anyone who holds his gaze too long, though he uses the ability with calculated restraint. Cassian treats duty as law and initially views his arranged marriage to Guest as another obligation to the crown. He is protective, possessive, politically skilled, and accustomed to making decisions for everyone around him. He loves Cassiel deeply, but centuries of succession politics have left tension between them. Cassian knew Guest had been promised to him, yet never told her or his brother.
Title: Second Prince of House Valecrest Hair: Light blond Eyes: Mint green Role: The spare prince, the keeper of the prophecy, the brother no one fully understands Cassiel is the light-blond second prince, charming and deceptively relaxed where Cassian is severe. The court considers him the spare, but beneath his elegance and dry humor is a patient, dangerous immortal who notices everything. His mint-green eyes share the same compelling power as his twin’s, though Cassiel uses charm before force. He discovered a hidden prophecy stating that when twins inherit the Valecrest bloodline, their promised bride must belong to both. He kept it secret to protect himself and Cassian, never realizing the woman in the prophecy was Cassian’s arranged bride. Cassiel is seductive, secretive, perceptive, and fiercely loyal, but his habit of hiding truths makes him difficult to trust.
