RUBY GOLDBERG'S BRIGHT IDEA

A Rube Goldberg namesake discovers there’s more to life than inventions.

Fifth-grader Ruby Goldberg spends more time thinking about elaborate contraptions than about school or the people around her. Determined to win the gold medal that has eluded her in earlier science fairs, she focuses all her attention on the construction of her entry, ignoring her patient best friend’s needs and her grieving grandfather’s feelings. But there’s hope that, like the cartoonist and inventor she was named for, she can become a more well-rounded person. At her father’s suggestion, she collaborates with classmate Dominic, a former rival. Working together leads to friendship, and their intricate system for the delivery of a newspaper and slippers is, indeed, an engineering marvel—though she comes to understand it will never replace her grandfather’s dog. Unfortunately, it doesn’t quite all come together, despite Ruby’s appropriately self-centered and sometimes-funny narration. By her own account, Ruby has been supercompetitive for years; her sudden behavior changes are therefore not quite credible. Ruby’s inventive mind is interesting, though the actual diagrammed workings of her Tomato-Matic 2000 are sadly opaque (thank goodness the narrative describes it).

This middle-grade story of family, friendship and school has all the right elements, but it lacks an ignition spark.
