[Siren LoveXtreme Forever ManLove: Erotic Alternative Fantasy Ménage Romance, M/M/M/M/M/M/M/M, demons] Hex and his six demon warriors escaped the depths of Tartarus under Hades' watchful eye to live among the mortals in the Top World. The Oracle has prophesized an epic battle to come—a war between good and evil that will test the warriors as never before. When Echo arrives on their doorstep, cold, naked, and hungry, they immediately realize he is their mate, and the prophesized “heart” that beats between them. Echo may be the ultimate weapon in the war, but he’s also a spitfire, and he instantly turns their world upside down. If fighting an angry god weren’t enough, the warriors learn Echo has escaped from a secret lab hidden away in the mountains, and it isn’t long before trouble comes looking for them. Can the demons keep their new mate safe when it seems the entire world—and the Underworld—is against them?
