Like countless teen sleuths before her, Chelsea Chance has solved her fair share of mysteries, but this is the big one: an adult film that actually kills the people who watch it! How? Why? Chelsea and her intrepid bestie Janet Watkins are determined to find out, but this time they're in WAY over their heads, and they'll be lucky to walk away from this supernatural mystery alive, sane, and not in the thrall of powers far beyond their straitlaced, teenybopper ken. "If Nancy Drew was a narcissistic sociopath, she still wouldn't be as crazy as Chelsea Chance. And that's exactly what makes this book so fun."
