Princeps fury by Jim Butcher

The provided excerpts chronicle a world ravaged by war against a formidable, insectoid enemy known as the Vord. Humanity, primarily the Aleran Empire, relies heavily on "furycrafting," a form of elemental magic, to combat the overwhelming Vord forces. Key characters such as Raucus demonstrate immense power in battle, wielding fire and wind furies, while Tavi, the Princeps of Alera, engages in both direct conflict and intricate diplomacy with the Canim, a wolf-like race, to secure their aid. The narratives also highlight Isana's political efforts to unite disparate factions, including the volatile Icemen, and the Alera's struggle with internal strife and the devastating impact of the war on its cities and people, revealing the high stakes and brutal realities faced by all.
