In a world where vampires reign supreme, humans are divided into two classes: the fortunate elite who live in relative normalcy, and the enslaved masses used as pets or slaves. Every four years, a grim lottery takes place in human cities, where ten young individuals between the ages of 15 and 20 are selected. Half are sold as slaves, while the rest are sent to pet shops, where vampires can purchase them at will. Blair Solace, a talented 19-year-old, finds herself ripped from her family and thrust into the cruel world of vampire dominance. She is purchased by Russel Huxley, the prince of the city, a powerful figure who revels in displaying his wealth and status. As Blair endures the harsh realities of her new life, her captor takes pleasure in showcasing her in extravagant attire. But everything changes between them, once an upcoming ball is getting prepared. And Russel decides for him and Blair to have matching outfits. For the first time in his whole life, he sees a human in her, and not just a regular pet. 'Their Blood' is a thrilling and poignant tale of resilience, passion, and the transformative power of love, set against a backdrop of tyranny and liberation. As Blair and Russel navigate their dangerous path, they must confront their own prejudices and the wrath of a society unprepared for the changes their union might bring. Will their love be the catalyst for a new era, or will it be their undoing?
