Ember in the Forge - H. T. Martineau - Bog

In her middle years, the mining dwarf Ember is well set in her ways. Her position as the master blacksmith of Eldur Hollow is a surety that has never been challenged. However, after Ember sees a green light cross the sky, she swings her hammer in her forge and sets the whole burrow ablaze, destroying all she has worked decades to create. Unbeknownst to any in Ambergrove outside the forbidden lands, the Age of Magic has begun.
Kaenye, the god of fire, is Ember's only hope at learning how to control her newfound magic and return to the life she's always known. With nothing but meager supplies and a command to find a woman in a red dress in Port Albatross, Ember leaves her home behind and ventures into a world that distrusts her and the destruction that unwittingly comes at her hands.
Ember is a maker, but harnessing her magic and convincing those she meets-and herself-that fire magic is not something to fear is a task for a giant, not a mining dwarf. As Ember relearns how to live, she also learns that magic has a purpose, and she is not the only one who needs to learn how to harness her fire.
This mining dwarf has her heart set on returning to the forge, but as long as there is an ember, the fire will burn-and the life within the flame is not always what we expect.
