Why Teens Love It
Pip is smart, stubborn and relatable, and readers love solving the mystery alongside her. The mixed format, with interview transcripts and evidence logs, makes it feel like a true crime podcast.

Is A Good Girl’s Guide to Murder Okay for a 12- or 13-Year-Old?
Some mature 13-year-olds read it, but the drug and assault themes and the strong language are significant. For 12-year-olds, it’s usually better to wait.
The sequels, Good Girl, Bad Blood and As Good as Dead, get darker, especially the final book, which many readers find much more intense.
