Liam is an ordinary IT employee grinding through a dull 9-to-5 when he accidentally finds a door on the 13th floor that opens into Hollowfell — a stormy, monster-filled realm where the ultra-wealthy elite hoard exotic women as trophies. Outraged and opportunistic in equal measure, he sets himself up as an outlaw thief, raiding the vaults of High Society monsters and rescuing their captives. With each heist, his growing crew of monster girls becomes both his best asset and his greatest motivation.

Liam is resourceful, irreverent, and surprisingly principled beneath his mercenary exterior — he may be in it for the loot, but he cannot walk away from women in danger. His knowledge of Earth technology gives him an edge in a magical world that has never faced a gun. Readers love his blend of competence, humor, and genuine loyalty to the people he rescues.

Across 8 books, Liam rises from a two-bit opportunist to the self-styled Outlaw King, building a magical army of followers and taking the fight directly to the High Society establishment that runs Hollowfell. The series escalates from personal heists to full-scale war, eventually unraveling the ancient secrets behind Hollowfell itself. The final volume delivers a satisfying, complete resolution as Liam and his companions secure the future of their found family.
