A Touch of Malice by Scarlett St Clair

Persephone and Hades are engaged. In retaliation, Demeter summons a snowstorm that cripples New Greece, and refuses to lift the blizzard unless her daughter calls off her engagement.

When the Olympians intervene, Persephone finds her future in the hands of ancient gods, and they are divided. Do they allow Persephone to marry Hades and go to war with Demeter or prohibit their union and take up arms against the God of the Dead?
