If you love a good mystery thriller, then "A Good Girl's Guide to Murder" (£7) by Holly Jackson is for you. The town of Fairview has its own true-crime tale: the murder of high school senior Andie by her boyfriend Sal, who then ended his own life. Five years later, another high school senior, Pip, reopens the closed case to prove Sal innocent. But, the deeper she digs, the more the case unravels — and the clearer it becomes that someone doesn't want her investigating.
