Persey Green is a teenage genius struggling to maintain average grades so she doesn’t stick out, her older sister recently died of a mysterious cancer-like illness, and her mom doesn’t seem to notice she exists. If dealing with survivor’s guilt and an increasingly distant mom isn’t enough, Persey develops a strange allergy to cold weather and snow.

Unfortunately, she lives in Montana and it’s the middle of winter.

She’s got a lot on her plate, but Persey is more concerned with Aides, the Greek exchange student who seems curiously interested in her, than the migraines that plague her every time it snows. Aides is tall, dark, handsome, and admittedly, more than a bit peculiar. But Persey feels a strange connection to him that both repels and intrigues her.

While she’s navigating the gamut of first love, Persey learns three disturbing truths. First, that through divine interference, Persephone, goddess of the Greek Underworld, was reborn in her. Second, Hades has returned to earth in the guise of an exchange student named Aides. Third, she is doomed to spend the rest of eternity as Hades’ bride in the Underworld.

Persey struggles for her independence in this strange new world, and although she revels in her growing power, she learns that her predecessor, Persephone, was driven mad by the dark influence of Underworld. She must make the ultimate decision. By staying with Aides, she risks her own sanity, but if she leaves she risks her life and the greatest love she’ll ever know.
