Twelve-year-old Claudia's father has mysteriously left, and she's staying with her grandfather. The intergenerational pair follows a scavenger hunt that ultimately reveals a truth Claudia's father has been hiding for a long time. The story is told in a multimedia format, including texts, video transcripts, and Claudia's "notes to the reader." Although this format is likely to appeal to young readers, it slightly impedes Claudia's character development.

Levine (The Lions of Little Rock) crafts a powerful puzzle of a novel about a missing father and his daughter-s search for the truth. The memorable narrator, 12-year-old Claudia, pieces together this -scrapbook- of a story through an inventive collection of notes to the reader, texts, emails, video transcripts, phone logs, Google directions, receipts, and other items. The fragments and ephemera serve to document and help Claudia to come to grips with the sudden, unexplained disappearance of her father. When Claudia-s mother must attend a work conference in Switzerland, Claudia has to stay with her introverted grandfather, Papa, who is still grieving the recent death of her big-hearted grandmother. As Papa and Claudia forge a closer relationship, she also meets a budding filmmaker, who helps her decipher the intricate clues that her father (a lover of brainteasers) left behind. Through the story-s patchwork format, Levine reveals characters- inner complexities while maintaining tension and uncertainty leading up to the story-s moving revelation. This taut mystery is also a portrait of a family coming to terms with truth and identity. Ages 10-up. Agent: Kathy Green, Kathryn Green Literary Agency. (June)

Gr 4-6 Unlike her previous two novels, Levine's latest is set in contemporary times, with email, text messages, and movie ticket purchases all very much part of the plot. The novel aggregates these mementos in the form of a scrapbook put together by 12-year-old Claudia, whose world has recently been rocked by her father's sudden disappearance. Confused and angry, Claudia decides to stay with her recently widowed grandfather rather than accompany her mom to an upcoming business conference. There, she meets Luis, a budding documentarian, and she also gets something weird in the mail: a puzzle piece, with the mysterious words "find the time capsule" scrawled on the back. Soon, Luis and Claudia begin following a convoluted trail of clues that seem to lead to a secret about Claudia's dad. Luckily, Luis, Claudia, and her grandfather (who provides the cache of home movies Claudia must examine for answers about her dad's childhood) are all assiduous collectors of detail, and, as we peer into Claudia's dad's adolescence, it becomes clear that his absence results from a long-repressed struggle with his identity and sexuality. Readers are treated to a fast-paced narrative filled with feeling and subtle family tensions. Levine's clever mixture of modesincluding screenplay, transcripts, text threads, emails, receipts, and first-person narration from Claudiaillustrate beautifully the ways multiple perspectives on a subject can provide a nuanced, vibrant picture. VERDICT Mystery lovers and budding filmmakers will love this well-paced, touching, and creatively executed coming-of-age tale. Abigail Garnett, Brooklyn Public Library.
