Hades by Ambrosia R. Harris

“Careful what you say, Goddess,” he breathed, “I may not let you leave.”…
A wicked smile spread her lips once more, “Perhaps it is you who should be careful, my king.”
Hades, the King of the Underworld and God of the Dead, had a lonely existence in his realm. Meeting and judging the shades, attending the few meetings in Olympus, and spending as little time in the mortal realm as possible. That is until Thanatos goes missing, Elysium begins to decay, and he is stuck leaving his realm to collect souls on the fates’ request.
His task was simple, retrieve Icarus and return.
But when he finds the young Goddess of Spring massacring a patch of wildflowers, he soon finds he is not the only Divine with Duality.
Over several chance encounters, he learns the sweet Goddess of Spring has far more to offer than dainty petals, and that her vengeance is just as insatiable as his.
