The Binding Song (Shadows of Unity Book 1) by Mira Dunne
Sable Corven hears everything. Every lie. Every secret. Every heartbeat through a wall. Classified as Minor Talent in a kingdom that ranks its mages like weapons, she has spent years being underestimated.
When she is paired with Commander Taran Valrath, a man whose gift is fire and whose presence disrupts every frequency she controls, she uncovers a conspiracy that spans all four kingdoms.
Built on a ritual that binds the soul and buries the will. Her magic is her weapon. Her voice is her weapon. The man she is falling for may be the most dangerous weapon of all.
A dark romantasy for readers who like their love interests morally complicated and their magic systems with teeth.
