Do you see the Light?
The Final Faith does, and so does Enlightened One Gabriella DeZantez, Sister of the Swords of Dawn. She sees the Light of God. She sees the Light of Truth. The Order of the Swords of Dawn have been the bane of heretics and apostates for as long as there has been a Final Faith, but when an assassin strikes at the heart of the Faith, it signals both a new threat and an ancient one.
Gabriella must eliminate the danger to the Faith, but what is the connection between shadowy assassins, fleeing refugees, and an ancient legend of an island made of diamond? The answers can only be illuminated by making everyone see the Light of God, the Light of Truth and, ultimately, the Light of Heaven.
