Who it's for, and whether it holds up.
The Lord of the Mysteries comparison will follow this novel everywhere, and it's fair. Victorian-esque occult setting, beyonder paths as the power system, a protagonist who survives on intelligence and planning rather than brute force. The influence is clear. What Dorothy's Forbidden Grimoire does with that foundation is carve out enough of its own identity to stand separately, at least for a while.
Dorothy herself is a solid lead. She's a transmigrator, but one who actually adapts and thinks, relying on careful maneuvering over coincidental power spikes. The antagonists are better than genre average: they have their own logic and don't simply exist to be defeated. The absence of a romance subplot is, genuinely, a relief.
The power system is interesting and the lore reveals come at a reasonable pace without turning into an encyclopedia dump. Action sequences have real tension. The first half earns most of the goodwill.
Where it slips is in the later portions. Pacing accelerates past the point where events have weight. Coincidences in the early chapters already stretch plausibility a bit, and the characters can feel thin under scrutiny, likable but not deeply drawn. Power scaling creep eventually turns what felt grounded into something more exaggerated.
This is a solid entry in the Victorian occult cultivation space. It doesn't reach the heights of what clearly inspired it, but it's well-constructed and worth the time for readers who enjoy the subgenre. Just expect a somewhat rougher ride in the back half.
