Everyone knows Y/N as Cassian’s little sister—the stubborn Illyrian warrior who can hold her own but has never quite stepped out of her brother’s shadow. Then she meets Helion, High Lord of the Day Court. He’s charming. Infuriating. Shamelessly flirtatious. And, unfortunately for Y/N, he’s also her mate. What starts with teasing, stolen glances, and a mutual refusal to admit their attraction quickly becomes something neither of them expected. Because beneath Helion’s golden smile is a male desperate to be loved for who he truly is. And beneath Y/N’s warrior exterior is a female who has been waiting for someone to see her—not as Cassian’s little sister, but simply as her. Sometimes, the sun finds exactly what it’s been searching for in the shadows.
