A CALCULUS OF ANGELS
1722: A second Dark Age looms after the devastating impact of an asteroid,
unnaturally drawn to Earth by dire creatures who plot against the world
of men. Yet this destruction is just the opening salvo in a war of

the Atlantic to discover what has befallen the Old World. With them
sails Red Shoes, a Choctaw shaman whose mysterious connections to the
invisible world warn him that they are all moving toward a
confrontation as violent as it is decisive...
