April Sakamaki was raised in a house of monsters—and loved them all. Adopted by the enigmatic Karlheinz Sakamaki, April believed herself human, cherished by six older brothers who hid their true natures behind cruelty, charm, and obsession. With her crimson hair, ocean-blue eyes, and a voice that could melt even the coldest heart, she became the light in a mansion of eternal night. But April’s bloodline carries a secret. She is the daughter of Lucifer Morningstar himself, hidden in plain sight. As the truth awakens within her, the fragile bond between her and the Sakamaki brothers shatters into dangerous new desires. Shu’s lethargic apathy conceals a possessive hunger. Reiji demands control, molding her into perfection. Ayato craves her praise and her body in equal measure. Kanato clings with eerie devotion, desperate to keep her from anyone else. Laito whispers seduction, intent on corrupting her innocence. And Subaru fights his violent instincts even as he yearns to protect—and claim—her. Torn between love and fear, duty and desire, April must navigate a twisted web of obsession where roses bloom black, secrets bleed red, and devotion blurs into possession. To survive, she must decide: will she remain the cherished “princess” of the Sakamaki household, or embrace the darkness of her birthright and risk losing herself to the vampires who love her too much to let her go? A gothic tale of forbidden love, betrayal, and temptation, The Diabolik Lovers and The Princess is an intoxicating descent into the beauty and terror of eternal night.

She was born royalty, raised in chains... and destined to set the world on fire. April Morningstar was only six when her pack was slaughtered and her identity buried. Branded an orphan Omega, she spent her life scrubbing floors and hiding her power in the shadows of the cruel Red River Pack. But beneath the silence lies a secret—she is the last pureblood Alpha, the Crimson Flame, and her wolf is a beast of legend. Jasper Black is ruthless, feared, and the Alpha of the powerful Black Claw Pack. When he returns to Red River for a diplomatic summit, he doesn't expect to find her—the ghost of his childhood, the girl he thought was dead, and the mate the Moon Goddess promised him. But April isn’t the broken girl he remembers. She’s on the edge of awakening, and when her true bloodline is revealed, she becomes the most hunted woman in the supernatural world. As deadly enemies close in and dark heat simmers between them, April must choose: surrender to her mate, or become the Alpha she was born to be. Because fate doesn’t ask nicely—and neither do monsters. In a world of savage bonds, brutal secrets, and primal desire... only the strong survive.
