In this thirteenth mystery, Sammy is entering eighth grade with more than the usual angst—add to it being a bridesmaid in Officer Borsch's wedding, dealing with the break-up of her friend Marissa's parents, and her own mother dating the father of arch-enemy Heather. How will she be able to solve the mystery of who's making death threats against the history teacher that nobody likes (especially with her name at the top of the suspect list?) With wit, style, and spirit as usual!
