A Sovereign of Death, bound by unyielding devotion, resists a temptation that could unravel eternity. A Sovereign of Sorrow dares to break the oldest law and love a mortal, only to learn that fate does not bend for desire. A Sovereign of Pleasure tempts mortals with delights that always demand their price. The lesson is eternal: fate always demands balance. The Mourner's Song is the prequel to Threads of Fate, a sweeping romantasy of desire, defiance, and divine consequence.
