In an alternate eighteenth-century Europe devastated by alchemical disaster, Sir Isaac Newton and his able assistant, Benjamin Franklin, confront enemies who seek humankind’s destruction
Sir Isaac Newton’s discovery of philosopher’s mercury in 1681 gave rise to a remarkable new branch of alchemical science. Forty years later, the world stands poised on the brink of a new dark age . . .
England is in ruins, crushed by an asteroid called to Earth by the very alchemy Newton unleashed. France is in chaos following the long-delayed death of Louis XIV. Cotton Mather, Blackbeard, and the Choctaw shaman Red Shoes set sail from the American colonies to investigate the silence lying over the Old World. And in Russia, Tsar Peter the Great, now host to the evil entity that kept the Sun King alive, seizes a golden opportunity for conquest as he marches his unstoppable army across a devastated continent.
Meanwhile Newton and his young apprentice, Ben Franklin, hide out in Prague, awaiting the inevitable violent collision of all these disparate elements—human and demonic alike—while a fugitive Adrienne de Mornay de Montchevreuil pursues the secrets of the malakim and her own role in their conspiracy to obliterate humankind.
The second volume of the Age of Unreason series, Greg Keyes’s masterwork of alternate history, A Calculus of Angels brilliantly expands the scope of the world he introduced in Newton’s Cannon as an unforgettable cast of historical heavyweights collide on a different Earth where magic and science coexist.

What if Isaac Newton had discovered that alchemy works? J. Gregory Keyes has based his Age of Unreason series on an alternate 18th century shaped by a "science" that grew from Newton's discovery of "philosopher's mercury," which "can transmit vibrations into the aether" and thus "alter the states and composition of matter." In A Calculus of Angels, Keyes continues the tale he began in Newton's Cannon. It's a satisfying sequel that nevertheless leaves the reader impatient for the next book.
Two years have passed since the asteroid struck. The weather is unnaturally cold, the skies perpetually overcast. England is devastated, the French government has collapsed upon the death of Louis XIV. Peter the Great, now inspired by the guardian spirit who preserved Louis, has marched his armies westward into the Netherlands and France. In the New World, the abandoned colonists send a delegation including Blackbeard, Cotton Mather, and a Choctaw shaman named Red Shoes to find out what's happened. In Prague, Newton and his apprentice, Ben Franklin, seek to protect the city from aetheric attack. The mathematically gifted Adrienne de Montchevreuil is also back and expanding her knowledge of the mysterious malakim who inhabit the aether and menace mankind.
Keyes creates a very believable mixture of history, fantasy, and plausibly imagined historical characters. Each book has been exciting, suspenseful, and beautifully written. No admirer of alternate history should miss this series. --Nona Vero
Praise for Greg Keyes
“A new myth-maker, a new star of the fantasy genre has arrived. Like Ursula Le Guin in the ’60s, John Varley in the ’70s, and Orson Scott Card in the ’80s.” —BookPage
