Magic isn’t a blessing when it costs your life. When a century-old war reignites and an army with magic-users invades, Prince Arran of Nithle must act quickly to protect his kingdom. But the enemy isn’t after his kingdom. They’re after him, and death is closing in faster than his inability to properly swing a blade. To ensure the prince’s safety until the threat has passed, the Union, an organization that safeguards all human kingdoms, sends a warrior with unmatched skills to act as his personal guard. Trained from birth to spill blood, Ryla’s expertise strikes fear in enemy forces as she meets their attacks at every turn. Arran’s efforts to better understand his protector lead him to uncover devastating truths about both her and the war. These are secrets that make the enemy bolder and cause fissures among his people. Secrets that—in the wrong hands—could lead to everyone’s undoing.
