The year is 1963, and the prison island is as full as ever. It’s an American fortress, housing some of the world’s worst criminal offenders of magic. They are brought here when Sanctuary jails are too full, to be kept isolated from the rest of the waking world both magical and mortal. But the island has grown too complex and vast to maintain. Some of the binding spells on the cellblocks are wearing off, allowing prisoners to begin displaying brief bursts of magic. The prison must be closed and the prisoners relocated before an all out catastrophe ensues.
Only one among them carries a price on her head, put there by a rival villain still at large. And it’s up to two very unique assassins to go in and kill her off.
This is a preview summary for the next chapter in FAFFL, pretty much stating what's going to happen. Sanguine and Mirage must somehow infiltrate Alcatraz before it closes, and make off with the head of their target with enough time left to escape. Or else be locked away themselves for the rest of their lives.
