Deadly Cool (Hartley Featherstone)

School Library JournalGr 8 Up—Hartley can't believe her bad luck. First, she hears rumors that her boyfriend, Josh, is cheating on her with Courtney Cline, a member of the abstinence-only Color Guard. Second, she finds an empty condom wrapper in his locker—maybe it doesn't mean anything, right? Finally, and this is the biggie, after she goes over to Josh's house to confront him, she finds Courtney dead in his closet, strangled by her own iPod earbuds. So, what's a jilted and traumatized girl to do? Prove her ex-boyfriend's innocence, of course. When Hartley and her best friend set out to discover who murdered the popular teen, they find themselves in more danger than they bargained for. After Hartley stumbles upon another murdered Color Guard member, she begins to suspect that she might be next on the killer's hit list.
