BLURB
A FATED LOVE.
A COSTLY BETRAYAL.
Fia Riftborne thought joining the Sídhe Guard was the hardest choice she'd ever make.
She was wrong.
Taken prisoner by those she swore to fight, Fia uncovers a devastating truth that upends everything she ever knew…about the Aossi…about Sídhe …about herself.
As war looms on two fronts and tensions in Sídhe reach a breaking point, the Void that gave Fia her power is calling—but answering it means betraying everyone she left behind.
The Guard. Her friends. Laryk.
In a war where nothing is as it seems, choosing the wrong side could cost her everything, including the brooding commander whose darkness seems to call to her own.

AUTHOR BIO
Bree Grenwich and Parker Lennox are two platonic soulmates who have been nearly inseparable since meeting at 19. Their shared love of fantasy, badass heroines, and steamy romances fueled their dream of co-authoring a novel, which they've finally achieved with their debut, Riftborne. When they're not conjuring worlds filled with female empowerment and swoon-worthy relationships, they’re binge-watching reality TV or obsessing over the last Dungeons and Dragons session.
