Evil Eyed by Joely Sue Burkhart

Three wishes for my leprechaun’s gold coin. One down, two to go…

I won. I defeated the changeling who’d been feeding on me. My treasures escaped the trap set by Balor’s dark fae. But now I don’t even know what I am.
Am I fae? Like the monster who trapped me in marriage and fed on me for five years? Or like my leprechaun, Warwick Greenshanks, who plays a delicate game of neutrality between dark and light fae? He swore to never lie to me, but he didn’t make that promise on his gold. Only his heart.
Balor of the Evil Eye is closer than ever to destroying the veil between the mortal realm and Faerie. The secret to defeating him is written in my very soul, but I have no idea what to do.
I don’t even know who—or what—I am, and each battle the four Irish treasures wage may be their last.
