I think you’re right on with the Leo for Apollo and the Taurus for Hades. I think it would be ridiculous if I made Apollo anything but a Leo, honestly.
Hades is absolutely an earth sign, can’t really be anything but, and I hadn’t really pinned Persephone for being a Scorpio but it makes some amount of sense.
I’m going to put that one out to everyone who follows me… what signs would you attribute to the major characters in my books?
