Beginning a generation before Hekate, Styx sings the story of the goddess of the underworld river that bears her name…

The firstborn child of Titans, Styx is revered as the first of her kind – until she is eclipsed and forgotten amid her scores of siblings, the Oceanids and the Potamoi.

Coming of age in a world simmering with paranoia and unspoken fear of Zeus, the volatile and unchecked god-king, Styx learns to conceal the rage ignited by her growing disillusionment with her parents and her vain and unkind siblings. Instead, she finds solace and sisterhood in her cousin, Asteria. Together, they train in the arts of creation and magic. And as they seek to learn their divine purpose and their place within the Titanomachy, they discover both the joy sparked by true love and the fierce resilience birthed from motherhood.

In this lyrical and heartrending tale of sisterhood, identity, love, and war, Styx must carve her own path to womanhood – and ultimately, godhood.
