The Light in Hades (Olympus Retold) by Elise Nelson

Correlia of Olympus was “gifted” the destiny of becoming Persephone, Goddess of Nature and Spring. As every Great One is told, she must follow the path appointed to her or the world will be off-balance. Beneath Mt. Olympus, Theron of Tartarus has been groomed to become Hades, the God of the Underworld. Despised by everyone on Olympus and tormented by his mentor, he has only known a life of abuse and despair. The two were never meant to cross paths, but when Theron is sent on a mission to Mt. Olympus, he finds the goddess who is meant to be his enemy and his greatest opposition. One encounter is all it takes for everything to change. Now, the sheltered Corre finds herself in a position she never could have imagined: falling in love with the God of Death and questioning everything. Even her destiny. The Light in Hades is a YA romantasy about forbidden love and finding belonging in a world of darkness. It features mental health topics and low spice.
