Onyx spent twenty years as a lab rat, her vampire blood studied, her body broken, her mind haunted by endless screams. Her only tether to sanity was her sister, Sky, locked away in a distant cell. When a final experiment threatens Sky’s life, Onyx unleashes a brutal, bloody escape, only to step from one prison into another: Dayken Danielson, a wolf-shifter guardian sworn to protect her. Now on the run from ruthless government hunters, Onyx is forced into the world of clan politics and uneasy alliances. Her trauma-hardened instincts clash with Dayken’s unwavering loyalty, and the constant threat looming over them is a reminder of everything she stands to lose. Yet the ancient bond etched into their skin doesn’t just bind them, it sparks with power… and with hope. As buried secrets surface, Onyx must confront her past to protect her sister, face the shadows of her past, and reclaim her shattered identity. And when Dayken proves that respect and loyalty can heal even the deepest wounds, trusting him may be her greatest act of courage yet.
