Broke art student Mia, secretly an angel hybrid with blood that drives vampires mad, moves into a cheap apartment only to discover her reclusive roommate Stefan is a cursed vampire prince. When her silver pendant shatters, unleashing her irresistible scent, Stefan loses control and bites her—only to scream in agony as her blood burns his mouth.
Trapped by a blood contract that covers her tuition and rent, Mia becomes Stefan's exclusive blood donor. Unlike terrified humans, she yells at him for ruining her carpet, sparking an unlikely bond. As Stefan fights his addictive craving and growing love, his tyrant mother Queen Victoria and jealous fiancée Roxie hunt Mia to steal her angel blood. When Victoria unleashes a blood demon, Mia awakens her full angel powers, merging her blood with Stefan's to grant him immunity to sunlight. Together they defeat the queen, forging a new era of peace—and welcoming a half-vampire, half-angel daughter who embodies their eternal love.
