Levius follows Levius Cromwell, a young man in a steampunk-inspired 19th century who uses a mechanical arm to compete in Gear Boxing, a brutal sport where fighters use steam-powered prosthetics. After a traumatic childhood, he fights to find his place and purpose in a world rebuilding from war. Readers enjoy it for its intense, well-choreographed boxing matches, stunning artwork, and a gripping, character-driven story that balances action with themes of resilience, human connection, and the struggle against corruption.
