Ink Shadow on the Book of Life and Death

When a glitch in the Book of Life and Death binds their fates together, an unhinged celestial official and a laid-back underworld boss find themselves sharing one life—literally. He destroyed her entire clan in their past life, yet now he's willing to betray the Heavenly Dao itself to save her. This enemies-to-lovers tale of vengeance, redemption, and reluctant partnership might be the only thing standing between the three realms and total collapse. Can love bloom when your soulmate is also your sworn enemy?
