Tae Keller’s newest middle grade book, Jennifer Chan Is Not Alone, opens with new girl Jennifer Chan declared missing at her middle school. As whispers begin, her next-door neighbor Mallory Moss worries that Jennifer may have been abducted by aliens (which Jennifer believed existed). Mallory reunites with two former friends begging them to help her find Jennifer following clues from her time with Jennifer and the diary Jennifer left behind. The story alternates between past and present as readers discover that Mallory’s search is also motivated by an ulterior motive: the need to prove that she and her popular friends didn’t run Jennifer Chan out of town with their bullying.
