BLURB
AN UNLEASHED POWER.
AN ALL-CONSUMING DESIRE.
Decades after a rebellion tore through the Isle of Sidhe, Fia Riftborne has learnt three important lessons to survival: keep your head down, don’t draw attention to yourself, and avoid the Sídhe Guard at all costs.
That isn’t so easy though when she harbours a secret power, one that would paint a target on her back if discovered.
Only, the swift punishment she expected never materialises. Instead, the elusive General Laryk Ashford offers her a choice: join the Sídhe Guard...or face execution.
Soon, Fia faces another impossible choice: surrender to the chaos within or become a weapon in the hands of those who took everything from her.
Including the alluring General who is starting to consume her every thought...

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.
