Ambriel's lonely life in Heaven collecting and cataloging magical objects never satisfied her, but it certainly suited her. Quiet, quirky, and largely ignored, Ambriel's angelhood is often the only connection she feels to her brother, the archangel Michael, who is running Heaven after the disappearance of God and Lucifer. But after a botched mission leaves an important artifact split between her hands and a demon's, Michael exiles her to Earth. A series of betrayals warp Ambriel into a devious enactor of revenge, determined to claim the vacant throne in Hell, and ensure she can never be cast out – or aside – ever again.
