A review by wealhtheow
Blood Engines by T.A. Pratt

3.0

Marla Mason has a problem. She may be the most powerful sorcerer in her city, but she has only days until a rival deletes her from existance. She and her faithful sidekick Rondeau (actually a parasitic spirit riding a chance-met human) travel to San Francisco to use the Cornerstone, a block of incredibly powerful magic. Getting the Cornerstone will be difficult--suriving San Francisco may be impossible. Sorcerers, gods, and technomages stand in Marla's way, and a fanatical priest of Tlaltecuhtli seeks to destroy the world.
This was an odd book, because the story begins very much in media res. Marla is far from a blank slate or a new to sorcery, and she's had years to build up allies and mortal enemies. The backstories were written a little clunkily, but I was glad to see them--I love complications and contradictions. Although the story takes place exclusively in San Francisco, Marla and Rondeau's reactions to another city tell the reader a great deal about their own city, Felport. The magics are ingenious and often inventive: one sorcerer lives on a train perpetually going widdershins, another operates under the principle that reality is a computer simulation of the past. Although the writing is a little rough, the action is exciting and Marla a great protagonist. Anyone who enjoyed early Laurell K Hamilton or Kelly Armstrong should give this book a try. (Note: this is not in the least paranormal romance.)
