When the light comes... pray for darkness. All Kagami Takeda wants is to be left alone, so that no one else can be destroyed by the madness she keeps at bay. Her connection to the Radiance--a merciless and godlike sea of light--has driven her family insane and given her lover strange abilities and terrible visions. However, the occult forces who covet her access to the Radiance are relentless in their pursuit. Worse, the Radiance itself has created an enemy who can kill her--a fate which would unleash its brutal light on a defenseless city.
