'And so a time will come to pass when the vanguard will emerge from the underground to battle the forces of darkness for the first of the final times. There will be five to face these foes. One to speak in tongues, one to cleanse in flame, one to stand beyond sight, one to read beyond the veil and one to move the earth.' In the city that will not drown but cannot swim, Sorcha Blades keeps her head above water by wheeling, dealing and stealing. But when an accident gifts her and four friends with talents their world has never seen, they must take a stand against the angels and their acolytes before everything they never knew they cared about is swept away.
