I think I'm gonna nominate two books, at least for now; one I've read and one in my TBR pile.
The Horns of Ruin by Tim Akers

Eva Forge is the last paladin of a dead god. Morgan, god of battle and champion of the Fraterdom, was assassinated by his jealous brother, Amon. Over time, the Cult of Morgan has been surpassed by other gods, his blessings ignored in favor of brighter technologies and more mechanical miracles. Eva was the last child dedicated to the Cult of Morgan, forsaken by her parents and forgotten by her family. Now she watches as her new family, her Cult, crumbles all around her.
When a series of kidnappings and murders makes it clear that someone is trying to hasten the death of the Cult of Morgan, Eva must seek out unexpected allies and unwelcome answers in the city of Ash. But will she be able to save the city from a growing conspiracy, one that reaches back to her childhood, even back to the murder of her god?
Thunderer by Felix Gilman

In this breathtaking debut novel by Felix Gilman, one man embarks on a thrilling and treacherous quest for his people’s lost god—in an elaborate Dickensian city that is either blessed …or haunted.
Arjun arrives in Ararat just as a magnificent winged creature swoops and sails over the city. For it is the day of the return of that long-awaited, unpredictable mystical creature: the great Bird. But does it come for good or ill? And in the service of what god? Whatever its purpose, for one inhabitant the Bird sparks a long-dormant idea: to map the mapless city and liberate its masses with the power of knowledge.
As the creature soars across the land, shifting topography, changing the course of the river, and redrawing the territories of the city’s avian life, crowds cheer and guns salute in a mix of science and worship. Then comes the time for the Bird’s power to be trapped—within the hull of a floating warship called Thunderer, an astounding and unprecedented weapon. The ship is now a living temple to the Bird, a gift to be used, allegedly, in the interests of all of Ararat.
Hurtled into this convulsing world is Arjun, an innocent who will unwittingly unleash a dark power beyond his imagining—and become entangled in a dangerous underground movement that will forever transform Ararat. As havoc overtakes the streets, Arjun dares to test the city’s moving boundaries. In this city of gods, he has come to search among them, not to hide.
A tour de force of the imagination, and a brilliant tale of rebellion, Thunderer heralds the arrival of a truly gifted fantasy writer who has created a tale as rich, wondrous, and captivating as the world in which it is set.
