Isabelle Harrington thought her biggest worry was her growing feelings for her best friend, Mike Wheeler. But when one of their friends goes missing, her problems seem to start growing and show no signs of stopping. Now, on top of those feelings, she's hiding a runaway, trying to keep The Party together, and running from The Bad Men. And to make matters worse, she's having to keep all this a secret from her older brother Steve Harrington. They've never been ones to hide things from each other, and she hates it. How is she supposed to manage all this?
