Shadows Lost: Remnant Archives Book 1 by B. K. Cavaleri

A curse that drove a queen mad. The heroine that failed to stop her. A shifter that refuses to give up. A world that needs them both again.

One hundred years after the Queen of Faerie sacrificed her own people in the name of salvation, the fae are on the verge of extinction and a suspicious power is on the rise. Remnant Ezra Solaire Dark, the once legendary war general, is the last of the shadow fae. Living in exile, only she holds the power to save the kingdom of Faerie. Enter Emon, a tempting shifter fae they call The Golden One who has been hunting for Remnant for the past century. When an unnatural power comes for them both, they must join together to reset the wrongs of the past in order to heal the future, not only for the world of Faerie but also for themselves.

Be warned. Remnant and Emon will journey through desolate lands long abandoned, to the shadowy underworld of the ocean, and into the dangerous kingdom of the shifters. This is no innocent adventure story. This is the world of the fae—power, vengeance, and half truths are the laws of the land. And the worst monsters are the ones hidden within.
