Book 1

Newton's Cannon

by Greg Keyes

Published 2 July 2004

Come on a journey sideways through time, and lose yourself in a world both deeply familiar and wondrously strange.

In 1681, Sir Isaac Newton turns his restless mind to the ancient art of alchemy, and successfully unleashes Philosopher's Mercury, the key to manipulating the four elements. Powerful kings will battle to control it, till London itself is threatened with obliteration by a hellish device - unless a pair of unlikely geniuses can defuse it in time.

This is a fantasy woven from the stuff of history, an enthralling quest whose outcome may raise humanity to unparalleled heights ... or bring down the curtain of endless night.

Book 3

Empire of Unreason

by Greg Keyes

Published 17 June 2005

When Sir Isaac Newton uncovered the secrets of alchemy, he could never have imagined the tragic results. Dark sorcery rules. Europe is lost and the American colonists have been driven south. The demonic creatures known as the Malekim won't tolerate even a flicker of hope. Any who oppose them - Franklin, Voltaire and even the mysterious daughters of Lilith - will be swept away.

However, Benjamin Franklin and his secret society, the Junto, manage a precarious existence founded on the mutual trust of Native Americans, whites, and freed blacks. And as armies and alchemy clash, the Choctaw shaman Red Shoes witnesses a vision of an ancient, implacable evil - and of a young boy who shines as brightly as an angel...the fallen, avaricious kind...

'An iconoclastic tale of science and sorcery leavened by a set of otherworldly villains offers deliciously skewed portraits of historical figures as well as a genuinely intriguing plot' Library Journal


Book 4

The Shadows of God

by Greg Keyes

Published 3 July 2001

As the ruthless forces of Russia lay waste to the New World, English troops make landfall in the east, determined to reconquer the colonies. Trapped in between are the Native Americans, ex-slaves, and European refugees, led by Benjamin Franklin and the Choctaw shaman Red Shoes. But the balance of power rests with the French woman Adrienne de Montchevreuil, whose grasp of science is the equal of Franklin's, whose magic may be stronger than the Choctaw, and whose shocking secret may call into question where her true allegiances lie . . .

'Inventive and exciting, filled with clever details and high adventure, this brings to a close a sequence that seems likely to establish Keyes as one of the more significant and original new fantasy writers to appear in recent years' Science Fiction Chronicle

'Thrilling . . . The book builds to a climactic confrontation to see who will reshape the universe' Publishers Weekly
