Dead of Spring by Colette Rhodes

For Kore’s entire life, her mother only ever wanted two things from her:
Swear an oath of virginity (to protect her from marriage)
Never show the world how much power she really possessed (to protect her from marriage)
Despite Demeter’s attempts to keep Kore as far away from Olympus and its capricious gods who might want her for their own, there was nothing in this world or any other that could have kept Kore hidden from Hades.
As for Kore, the more time she spends in the underworld, the more she realizes how alone and misunderstood its ruler truly is.
With her heart and all of humanity on the line, will Kore embrace her former life as The Maiden, or a future as the Bringer of Destruction?
