ER nurse Kira Rivers feels like a bad person because she’s dating three different men and can’t choose. The truth is much bigger: she’s a sleeping Nephilim, and all three men are her fated mates—Damon(vampire prince), Zane(son of a devil), and Leo(alpha werewolf). Vampires and devils have hated each other for 800 years and are not allowed to even speak because of an old treaty. When the men find out about each other, that old hate flares up again. The unfinished mate bond is slowly killing all four of them. To finish the bond and save everyone, they would break the treaty and risk starting a huge supernatural war. Kira has to decide: save the men she loves and maybe destroy the world, or let them die to keep the peace. They tell her she must pick one. But what if she picks all three?
