The Final Strife (Ending Fire series Book 1)

"The Final Strife was one of the strongest debuts I ever read, unfolding in the Wardens’ Empire, where people are divided based on the colour of their blood. The ruling class, the tyrannical Embers, have red blood; below them in the hierarchy are Dusters, with blue blood; and the lowest group are the brutally oppressed Ghostings, with clear blood. According to the law, only Embers can use the magic of bloodwerk. Sylah, an Ember raised as a Duster, was destined to be the Chosen One who upended the system, but something went terribly wrong. She knows how to nail a twist that wrenches your breath away, and all of her characters are deeply human, with genuine flaws to balance their strengths. Her worldbuilding is vivid and original, her stories are well-paced, and her imagination is boundless. In short, every ingredient of her books hits the spot."
