On the other side of Medio's border wall, the oppressed class fights for freedom and liberty, sacrificing what little they have to become defenders of the cause. Carmen Santos is one of La Voz's best soldiers: she spent years undercover, but now, with her identity exposed and the island on the brink of a civil war, Carmen returns to La Voz's headquarters. There she must reckon with her beloved leader, who is under the influence of an aggressive new recruit, and with the devastating news that her true love might be the target of an assassination plot, culminating in an excruciating question of loyalty -- to her cause or to her love.

Sequel to: We set the dark on fire.
