The hero of this funny, kindhearted novel is HD Schenk, a 12-year-old self-proclaimed -black geek--he-s a biracial German-American- who dreams of building his own computer with help from his understanding parents, his best friend Eli, and others in his small town. His summer takes a turn when he discovers an old pickling crock among his late grandmother-s belongings. -All pickling crocks are haunted,- says a local mystery writer. Enter Marietta, the ghost of his German great-great-grandmother, who has an agenda of her own: get other to make her famous sauerkraut and win the title of Pickle Queen at the county fair. Jones weaves identity into the story seamlessly, and offers a model for incidental representation: the diverse cast of characters (including HD-s disabled veteran father and gay uncles, and Eli, who grapples with a learning difference), encounter casual racism as well as brief ableism and homophobia, but these incidents are more like bumps in the road than central plot points, and HD and company confront them swiftly and effectively. Jones-s nimbly constructed plot features no adversary beyond competing needs for time and attention in a happy family, and it doesn-t bother with the usual conflicts about who can see the ghost (everyone, eventually). Celebrating the collision of old and new worlds, this simple but smart saga will appeal to kids who like their ghost stories more sweet than sour. Ages 8-12. (Sept.)

Gr 3-6 Maker and superhero-loving HD Schenk has a plan to build his own computer from scratch and enter it into the county fair this summer. But first he must earn enough money to buy parts, so he offers to help clear out his uncle's basement. On his first trip downstairs, HD encounters a ghostly voice. When he finds an old pickling crock that had been used by his great-great grandmother (Oma) to make sauerkraut, HD realizes that Oma is haunting the crock and she has a singular mission: to enter her sauerkraut in the county fair and win. As the only person who can hear Oma's voice, HD is compelled to help her but has trouble balancing his own dreams and goals for the summer with the demanding Oma's. Instead of keeping Oma a secret, HD introduces her first to his best friend Eli and then to his family and trusted members of his community. Oma is a strong enough ghost to work a pencil (among other kitchen equipment) and communicates with everyone through notes. This thoroughly quirky tale highlights the importance of mutual respect, community, and family heritage. HD, who is biracial and bicultural (black and German American), must constantly explain why he doesn't look like his dad, and has integrated his parents' different cultural backgrounds into his worldview. The grown-ups encourage HD and his friend to make time for their own goals and summer plans and respectfully accept Oma into their lives. Lists and plans and scientific observations of various projects are featured throughout, as well as warm, evocative pencil illustrations by Davey. VERDICT A ghost story about family heritage and obligations that will appeal to fans of family-driven, slice-of-life tales. Kristy Pasquariello, Westwood Public Library, MA
