Lord of the Underworld: Curse of the Gods Book 4

Hades was cursed to an eternity in the Underworld. Not that he had any interest in going topside anyway. At least, not until the day his reluctant wife, Persephone, goddess of spring, did not return as scheduled at the end of summer. He told himself that it didn't matter, that he didn't care- but what if she were in danger? Her own curse was tied to his and she didn't have a choice but to return. Right? And if she doesn't return, spring will die. Hades finds that he will do anything to keep her from harm, including breaking out of the Underworld and canvasing the whole of the Earth to find her. Can Hades find the key to breaking his curse in time to save the goddess of spring and the rest of the world too? Or will everything that is life in the world die?
