The way these rating read, you either love or hate this interpretation of the myth. I personally enjoyed the story, the repurposed OG mythology roots, and the romance combined with the Persephone's character growth.
In terms of the OG myth, it does in fact open an abduction (My earliest encounter with the myth showed Persephone innocently picking flowers in broad daylight. Suddenly, a chariot, spear-headed by dark horses, rips out from the ground, its drivers scoops her up and disappears back into the ground once more). Here, we see Hades, going unnamed for the first chapter and a half, watching a young woman simply named Kore (we'll get there), mulling over the morality of this deal with Zeus. I like that it's still a shock for Persephone to be with Hades, and she calls out the absurdity of his "could you be my wife and queen?" question. She's right to say it's too much to consider signing her life away to a man she's known for about a day.
The romance is so sweet, with Hades being open with Persephone, and really leans into the interpretation of their marriage being one of fidelity, respect, and equality. Hades needs a competent queen to help feed his Underworld population. One aspect I loved that's been tweaked is unlike OG Hades who is kind of just lonely/seeking companionship, this Hades is that as well, but his kingdom only sprouts jewels from the ground. Lovely as they are, they're not edible. Persephone's the Goddess of Corn and fertility, able to quicken the earth's seed. But she's been under Demeter's thumb for so long, she's not really been able to relish in her hard work. Side note, love the transformation she undergoes after two springs of being Queen Persephone. While searching for Kore, Hermes is watching a woman basically professionally work a room while sitting beside the man he knows is Hades. Hermes is flabbergasted/impressed that Kore could become Persephone, have her and the Underworld thriving in tandem.
The book reads like a trek to get to know each other and get back to each other, which could get tedious... but it is in fact the myth. We get bits and pieces of Persephone thriving as queen, and Demeter's crazed chase to retrieve her daughter. It's also written through the lens that Demeter is a narcissistic mother, given the line "My body was wracked with pain to bring you to life. I deserve your love!" and her refusal to see any man who seeks to love Persephone as hinderance to Demeter/taking Persephone from her, rather than letting Persephone explore a new phase of life. It's also worth noting that Demeter straight-up infantilizes/demeans Persephone; Hades is angered that before him, Persephone is given the name Kore that literally just means "girl", and upon her return, Demeter attempts to comfort Persephone by calling her Kore once more and cuddling her with promises of "mother's here". Meanwhile, Persephone is on the hunt to return to her man/views her mother as a smother.
Really liked the view on "everyone in the underworld is dead"; Hades argues that they're simply not living above ground anymore, but that they're going on about life down here. Gives a less doom and gloom finality of death/himself as a whole. He's not among corpses, nor is he one; they're just in another plane of existence. I kinda like that idea.
Loved that Hades did in fact want Persephone to feel like she had a choice in her stay; he goes "if you want to go home, I can make it so. Though it will break my heart, yours is more important". And he goes to Demeter himself, offering her lace for visiting when it's too hard for Persephone to face her mother. And that by the end, it ends with a firm deal: Persephone will essentially just quicken the upper world's seed/see to the harvest, but really, she lives with Hades. It's a tense "make her shut up" kind of ending that makes sure Demeter doesn't get pacified for throwing a tantrum.
All in all, I'm ready to read this author's take on Eros and Psyche. Still unsure of Orpheus and Eurydice, though...
