The Underworld Saga was originally published in 2013-2015 under the pen name Tempest C. Avery, with the final book Unabated arriving much later in 2021 to complete the four-book series. Spencer’s deal with Hadrian (Hades) drives the story: one year of nights in the Underworld in exchange for her boyfriend’s life.
The series was one of Feener’s earliest published works, predating her Xenith Trilogy by several years. The mythology retelling, particularly the portrayal of Persephone as evil, set the tone for the morally complex character dynamics that would define her later dark romance catalog. Later editions were rereleased under her real name.
