The North Wind by Alexandria Warwick

Long before civilization, there were the gods. And before the gods, there was the earth, the celestial bodies, and air given flesh. They are the Anemoi—the Four Winds—and they have been banished to the four corners of the world.
Wren of Edgewood is no stranger to suffering. Her parents are gone. Survival is all she knows. For three hundred years, the land known as the Gray has been encased in ice, surrounded by a great barrier called the Shade, which protects the townsfolk from the Deadlands beyond.
But day by day, the Shade weakens.
Only one thing can stop the Shade’s fall: a mortal woman taken captive across the barrier, bound in wedlock to the dark god who reigns over the Deadlands. He is the North Wind, the Frost King, an immortal whose heart is said to be as frigid as the land he rules.
And the time has come for the Frost King to choose his bride.
