As Good As Dead -By Holly Jackson

Pip is about to head to college, but she is still haunted by the way her last investigation ended. She’s used to online death threats in the wake of her viral true-crime podcast, but she can’t help noticing an anonymous person who keeps asking her: Who will look for you when you’re the one who disappears?
Soon the threats escalate and Pip realizes that someone is following her in real life. When she starts to find connections between her stalker and a local serial killer caught six years ago, she wonders if maybe the wrong man is behind bars.
Police refuse to act, so Pip has only one choice: find the suspect herself—or be the next victim. As the deadly game plays out, Pip discovers that everything in her small town is coming full circle . . .and if she doesn’t find the answers, this time she will be the one who disappears
