A series that reaches a seventh instalment has already answered the only question that really matters: people kept coming back. Judicator Jane began as portal fantasy with game mechanics bolted on, the sort of story where somebody from our world wakes up somewhere else with a menu hovering in front of them, and it has been building ever since.
Brian Rouleau writes it in a light register, with the comedy coming from the gap between the rules of the world and what the heroine decides to do with them. That is the whole appeal of the LitRPG shelf when it is handled well, and it explains why this run keeps finding listeners.
