- You like character-driven stories where the detective work matters as much as the magic system
- You're after a series with strong female leads who've earned their competence through failure and survival, not just natural talent
Maybe not for you if...
- You prefer cosy mysteries with lighter stakes and less supernatural danger
- You want a standalone book rather than investing in a series
