About Grimoire Guide

Grimoire Guide exists because the question "is this book appropriate for my kid?" shouldn't require an hour of googling, scrolling through spoiler-filled Reddit threads, and crossing your fingers.

Amazon doesn't tell you a book has graphic sex scenes. Goodreads doesn't warn you about genocide depictions. Neither platform tells you whether a "fantasy" book is actually a romance novel with a dragon on the cover. We do.

What makes us different

Every book in our directory gets a content rating (G through NC-17), granular violence/sexual content/language scores, trigger warnings, positive tags, trope labels, and an age group recommendation. We pull data from Common Sense Media, DoesTheDogDie, The StoryGraph, and our own editorial review process.

Our rating system

GSuitable for all ages. No concerning content of any kind.

PGSafe for most readers. Mild fantasy peril, no graphic content.

PG-13Best for teens and up. Moderate violence, mild romance, some darker themes.

RAdult content. Explicit sex, graphic violence, or strong language.

Hard RIntense mature content. Graphic gore, extreme violence, disturbing themes.

NC-17Most extreme content. Very graphic in violence, sex, or both.

Data sources

Book metadata comes from Open Library. Age ratings are cross-referenced with Common Sense Media. Trigger warnings are sourced from DoesTheDogDie.com (80+ categories) and The StoryGraph. Tropes and synopses come from TropeTrove and editorial review. Where data gaps exist, we use AI-assisted analysis and flag those ratings for community review.
