Countless mystery-thriller authors have cult followings and ascend to the top of bestseller lists, but not all of them straddle YA and adult audiences. British phenom Holly Jackson, however, does—and has followed all of the clues and gathered all of the evidence to know how to be damn good at it.
In less than a decade, Jackson has become one of the top-selling crime authors in the U.K., thanks in part to her largely teen-girl readership, whom she reveres and have followed her with each release since her 2019 debut, A Good Girl's Guide to Murder. The book, following teenage detective Pip's investigation into a cold case, peaked at No. 1 on the New York Times Best Sellers list, where it spent over 77 weeks, and its Netflix adaptation went on to reach No. 1 on its streaming charts in roughly 80 countries.
