But when his half-brother, the Sun King, summons him home, his carefree existence is abruptly interrupted. Tasked with locating Lady Eriana-a half-human, half-Fae noblewoman who has gone missing in the human realm-Taliesin embarks on a perilous journey, accompanied by the king's loyal guard and the enchanting Lady Delphina. All signs point to the Court of Underlings, a shadowy faction that poses a grave threat to both Fae and human alike.

Meanwhile, Prince Aven of the human kingdoms harbors a dangerous secret-he possesses magic, a gift viewed with deep suspicion across the land.
