The Traitor's Kiss (Traitor's Trilogy, Bk. 1)

With a sharp tongue and an unruly temper, Sage Fowler is not what they’d call a proper lady - which is perfectly fine with her. Deemed unfit for a suitable marriage, Sage is apprenticed to a matchmaker and tasked with wrangling other young ladies to be married off for political alliances. She spies on the girls - and on the soldiers escorting them.

As the girls' military escort senses a political uprising, Sage is recruited by a handsome soldier to infiltrate the enemy ranks. The more she discovers as a spy, the less certain she becomes about whom to trust - and Sage becomes caught in a dangerous balancing act that will determine the fate of her kingdom.

With secret identities and a tempestuous romance, Erin Beaty's The Traitor’s Kiss is full of intrigue, espionage, and lies.
