Has Anyone Seen Jessica Jenkins?

Kessler (the Emily Windsnap books) returns to familiar themes of uncovering hidden secrets and the value of friendship. Geography class is dragging on when 13-year-old Jessica Jenkins is called out for nodding off. But what she didn’t notice—and her best friend Izzy did—is that part of Jessica’s arm disappeared while she was snoozing. Thus begins a tale that’s part mystery, part science experiment, and a big leap of faith. Through trial, error, and coincidence, Jessica and Izzy learn that Jessica can make herself invisible, thanks to a rose quartz necklace given to her by a family friend, the midwife who helped deliver her. The plot becomes even more labyrinthine as circumstances reveal that a secret serum reacting with various crystals has imbued other kids with powers like levitation and mind-reading. Though the suggestion of supernatural or magical elements intrigues, the strained explanations Kessler uses to ground her story slow her storytelling and diminish the book’s lightness of tone. A somewhat ambiguous conclusion hints at potential additional adventures for this newly formed group of friends/superheroes. Ages 8–12. Agent: Catherine Clarke, Felicity Brian Literary Agency. (Feb.)
