CITLALLI ALVAREZ HAS RESCUED HER SISTER, became Alpha of the Seoul werewolf pack, and restored balance to the spirit world of Eve—all while waiting tables on the weekends. However, she still can't go to the Boryeong Mud Festival like a normal eighteen-year-old, not when her friend Una is a prisoner of a nine-tailed fox and the side effects of having a broken soul have begun to splinter her personality irreversibly. Then there's that little matter of being life-bonded to Vampyre Prince Khyber, whom her former flame Rafael has vowed to destroy no matter what. Priorities, priorities.

Meanwhile, Raina Alvarez meets her father's family, the prestigious and secretive Yong clan, who teach her the responsibilities that come with being the new Spring Dragon. In order to take her place amongst the Celestial Dragons who oversee the turn of the seasons, Raina must compete in the Trials of Wisdom against her three cunning dragon-shifter siblings and face her fears of Eve.

However, not everyone is happy about the rise of a Celestial Dragon in the East. Gods of blood and nightmares stir in the West. Old enemies join forces with ruthless new ones, eager to fill the power vacuum the Vampyre Queen left behind.

After all, the only thing standing in their way is a pair of sisters.
