Seraphina lives a sheltered existence as a high priest's daughter until ancient covenants require a virginal offering to pacify Lucifer, the cursed monarch of the underworld. Handed over in bridal white by her own ambitious family, she expects relentless torment inside his obsidian castle. Instead, she finds a brooding, sophisticated sovereign whose relentless attentiveness gradually strips away her terror, sparking genuine passion between mortal and demon.
Their blooming love turns tragic when an ancient grimoire unveils the horrific clause behind Lucifer's salvation: breaking his millennium-long curse requires the sacrifice of the person he loves most. Realizing that consummating their bond will destroy either Seraphina or the underworld king, the two lovers must navigate dark infernal politics and defy heavenly laws to rewrite their doomed destiny.
