Yukki GoKegawa has always stood out—But being chosen by heaven is a bit much.

Raised to be seen but not heard, unless singing in the choir, Yukki struggles to walk the delicate line between a traditional mother and doting father. But when a blinding light pierces her nights and a voice calls her by name, she finds herself drafted into a secret war between angels and demons.

Thrust into the secret order of the Maidens of Maria, Yukki discovers that spiritual warfare isn't just something the preacher rants about on Sunday morning. With her two closest friends at her side, and a no-nonsense guardian angel at her back, Yukki must face terrifying truths, buried strength, and the weight of a divine mission she never asked for but can no longer ignore.

Faith will be tested. Bonds will be broken. And salvation won’t come without blood.
