The Archive Undying (Downworld Sequence #1) by Emma Mieko Candon

War machines and AI gods run amok in The Archive Undying, national bestseller Emma Mieko Candon's bold entry into the world of mecha fiction.

WHEN AN AI DIES, ITS CITY DIES WITH IT
WHEN A CITY FALLS, IT LEAVES A CORPSE BEHIND
WHEN THAT CORPSE RUNS OFF, ONLY DEVOTION CAN BRING IT BACK
When the robotic god of Khuon Mo went mad, it destroyed everything it touched. It killed its priests, its city, and all its wondrous works. But in its final death throes, the god brought one thing back to life: its favorite child, Sunai. For the seventeen years since, Sunai has walked the land like a ghost, unable to die, unable to age, and unable to forget the horrors he's seen. He's run as far as he can from the wreckage of his faith, drowning himself in drink, drugs, and men. But when Sunai wakes up in the bed of the one man he never should have slept with, he finds himself on a path straight back into the world of gods and machines.
The Archive Undying is the first volume of Emma Mieko Candon's Downworld Sequence, a sci-fi series where AI deities and brutal police states clash, wielding giant robots steered by pilot-priests with corrupted bodies.
Come get in the robot. Hardcover; 496 pages
