Girl Last Seen by Heather Anastasiu, Anne Greenwood Brown

Kadence Mulligan's star was rising. She and her best friend, Lauren DeSanto, watched their songs go viral on YouTube, then she launched a solo career when a nasty throat infection paralyzed Lauren's vocal chords. Everyone knows Lauren and Kadence had a major falling-out over Kady's boyfriend. But Lauren knows how deceptive Kadence could be sometimes. And nobody believes Lauren when she claims she had nothing to do with the disappearance.
