Korean folklore and modern culture entwine in this epic fantasy about a reluctant heroine who must deny her fated love to battle the dark forces that threaten to end her worlds.

Nine-tailed fox spirit Sunny Cho has spent years running from her destiny, but fate is upon her. Inevitable or not, she doesn’t like it one bit.

After a harrowing battle with a dark enemy from her past, Sunny has nowhere left to go but back to the Realm of Four Kingdoms. She grudgingly trains as a suhoshin cadet by day while learning to harness the Yeoiju’s magic by night…to disheartening results. At least throwing herself into training with Jihun and her suhoshin friends keeps her from running to Ethan—a love that can never be.

But there are more immediate dangers to fear than the slow fracturing of her heart. Tyranny, deadly secrets, and betrayal reign in the Realm of Four Kingdoms. And eternal darkness threatens magical and mortal worlds alike. To stop the rise of evil, Sunny must embrace the full force of her powers…or risk being consumed by the darkness within.
