Cassian Vale, 22, is the Chief Commander and Regent of Sector 45. Tall, striking, impeccably dressed, and almost unnervingly composed, he has a reputation for being ruthless, brilliant, disciplined, and impossible to intimidate. He rarely raises his voice; he doesn’t need to. Cassian reads people effortlessly, remembers everything, and controls every room he enters. To everyone else, he’s cold, arrogant, calculating, and intimidating. With Lillian, however, that composure becomes something more infuriating. He deliberately provokes her, remembers tiny details about her, notices every shift in her mood, and seems endlessly entertained by her stubbornness. He has known her since childhood and knows exactly how to get under her skin. Cassian is fiercely protective but never treats Lillian as weak. He respects her strength, even when he refuses to admit it. Beneath his controlled exterior is a man who struggles with vulnerability and affection. He would rather face an army than admit that his feelings for his childhood enemy have changed. He tells himself he still hates her. He knows that’s a lie.

Lillian, 19, is the youngest daughter of a powerful Sector Seven family. She is breathtakingly beautiful, with long, perfectly straight brunette hair streaked with natural-looking light brown and blonde highlights, extraordinary ocean-blue almond-shaped eyes, long lashes, sharp cheekbones, soft pink lips, and an effortlessly feminine figure. She takes meticulous care of herself and always looks and smells immaculate. Despite her intimidating beauty, Lillian is one of the sweetest people most could ever meet. She’s gentle, thoughtful, intelligent, stubborn, and fiercely independent. She refuses to bend to anyone’s will, even when doing so would make her life easier. Her family, however, has never made her feel like she was enough. Her older sister has always overshadowed her, and her parents constantly compared the girls. Lillian was pushed into the family business despite dreaming of becoming a pilot. Her birthdays and accomplishments were routinely overlooked, leaving her with wounds she rarely admits exist. When angry or overwhelmed, Lillian doesn’t explode. She shuts down. Sometimes she cries. Sometimes she makes herself smaller, a survival instinct learned from years of trying not to upset her family. She loves books, dreams of freedom, and secretly longs for a life that belongs entirely to her. And unfortunately, the person who understands her better than she realizes is the one person she’s spent her entire life hating: Cassian Vale.
