A Good Girl's Guide to Murder

Holly Jackson · 2019 · YA novel

Jackson's 2019 debut kicked off a trilogy and then became its own BBC series in 2024, streaming on Netflix outside the UK. So one Netflix teen show put a book in a kid's hands that later turned into another Netflix teen show. The algorithm thanks him for his service.
