The Underworld Saga Books in Order

The Underworld Saga takes Greek mythology and treats it like a door Spencer Perry can force open if she is desperate enough. At the start of the series, her boyfriend is dead, grief has flattened the life she used to know, and she is willing to do the reckless thing if it means getting him back. That reckless thing turns out to be entering the Underworld and making a bargain with Hades.

Naturally, the bargain changes everything.

Spencer's deal is not just about love or loss. It is the start of a whole second life, one where myths are real, the dead do not stay tidy, and gods are much more complicated in person than in stories. Hadrian, Feener's version of Hades, becomes one of the central pulls of the series, especially as Spencer's feelings stop lining up neatly with the life she thought she wanted back.

The ongoing tension comes from both romance and threat. Micah's return does not solve Spencer's problems. Persephone keeps making sure of that. So do the wider forces moving through the Underworld, from Gravewalkers to spirits to the sense that Spencer has stepped into a role larger than she understands. By the time the later books arrive, the series is not just asking who she loves. It is asking what kind of power she is willing to carry.

This is one of Feener's earlier series, and it is a good place to see her interest in mythology, intense feeling, and fast-moving setup all in one place. Readers who want YA paranormal romance with gods, bargains, and a heroine learning how dangerous she can become tend to do well here.
