11 parts Ongoing After the Great War, the Olympian gods initiated the Time of Separation, dividing two worlds: the Mortal World, devoid of magic and reserved only for humans, and the Outer World, where chaos reigns freely. Five hundred years later, an unexpected crack in the magical barrier allows the dark creatures of the Outer World to threaten the Mortal World, though the gods remain unaware of this looming danger.
Deryn, a young mortal woman, finds her life abruptly changed when a powerful force from the Outer World-one of the greatest powers of the three worlds-unintentionally becomes bound to her body, and she finds herself in the heart of the Outer World. This power, known as the Prime Flame, has been hunted by the dark creatures of the Outer World ever since it was stolen from its place of safekeeping, making Deryn a target for those who seek to claim it.
In a world ruled by darkness, the only one who can help Deryn survive is the last remaining god in the Outer World. The God of Light, one of the most favored and powerful immortals of Olympus, offers Deryn a deal. He will help her return the Prime Flame to where it belongs and rid herself of its burden, and in return, Deryn must help him find the lost love he has been searching for centuries. As they embark on their perilous journey to restore the Flame, the bond between them grows increasingly complex, and a palpable attraction forms between Deryn, who has never trusted the gods, and the God of Light, desired by all the women in the three worlds. This attraction deepens as they share challenging experiences and come to rely on one another. In a journey filled with lies, secrets, and dangers, the only way for them to get what they want is to trust each other-no matter what.
