Souls in the Great Machine
by Sean McMullen

Description:
The great Calculor of Libris was forced to watch as Overmayor Zarvora had four of its components lined up against a wall and shot for negligence. Thereafter, its calculations were free from errors, and that was just as well - for only this strangest of calculating machines and its two thousand enslaved components could save the world from a new ice age. In Sean McMullen's glittering, dynamic, and exotic world two millennia from now, there is no more electricity, wind engines are leading-edge technology, librarians fight duels to settle disputes, steam power is banned by every major religion, and a mysterious siren "Call" lures people to their death. Nevertheless, the brilliant and ruthless Zarvora intends to start a war in space against inconceivably ancient nuclear battle stations. Unbeknownst to Zarvora, however, the greatest threat to humanity is neither a machine nor a force but her demented and implacable enemy Lemorel, who has resurrected an obscene and evil concept from the distant past: Total War.
