Embrace the Dark by Elizabeth Briggs

I’m the daughter of heroes. I’ve trained my entire life to take my mother’s place as guardian of the world. I’ve prepared myself for being mated to four dragon shifters.
But nothing could prepare me for this. I’m not mated to four men, but five.
The Death Goddess has chosen her own champion and demands I take him as my mate too. If I refuse? She’ll unleash the realm of the dead upon my world.
Too bad he’s the cruelest man I’ve ever met, and I want absolutely nothing to do with him. Neither do my other mates. But we’ll have to find a way to embrace his darkness…or watch the world fall into chaos once again.
