Liam Hamilton, a middle-aged man reborn as the fifth son of a collapsing noble house, finds one upside to his new life: free time to study magic. With a desperate father and indifferent brothers offering no guidance, Liam teaches himself from scratch, and his unexpected aptitude for spells the nobility considers beneath them begins drawing attention well beyond the crumbling Hamilton estate.
