Shorefall

As a magical revolution remakes a city, an ancient evil is awakened in a brilliant new novel from the Hugo-nominated author of Foundryside and the Divine Cities trilogy
 
Having narrowly saved the metropolis of Tevanne from destruction, Sancia Grado and her allies have turned to their next task: sowing the seeds of a full-on magical-industrial revolution. If they succeed, the secrets behind scriving—the art of imbuing everyday objects with sentience—will be accessible to all of Tevanne’s citizens, much to the displeasure of the robber-barons who’ve hoarded this knowledge for themselves.  
 
But one of Sancia’s enemies has embarked on a desperate gambit, an attempt to resurrect a figure straight out of legend—an immortal being known as a heirophant. Long ago, the heirophant was an ordinary man, but he’s used scriving to transform himself into something closer to a god. Once awakened, he’ll stop at nothing to remake the world in his horrifying image.
 
And if Sancia can’t stop this ancient power from returning? Well, the only way to fight a god…is with another god.
