A Good Girl's Guide to Murder

A clever, fast young adult mystery told through a project log and interview transcripts, with a great narrator and a surprising ending. It is darker than its cover suggests. Four out of five. Read it if: you like teen detectives and cold cases; you enjoy mysteries told through documents and transcripts; you watched the bbc and netflix series and want the original; you want a twist worth arguing about. Skip it if: drugging and sexual violence are hard lines for you; you want a gentle cosy mystery; you dislike a lot of suspects and red herrings; you need every decision a character makes to be sensible.
