THE MAZE OF BONES

The wildly popular 39 Clues series is adapted into graphic-novel format.

Orphans Amy Cahill and her younger brother, Dan, attend their grandmother’s funeral and learn that not only is the Cahill family tree larger than they knew, but that Grandma left each of them a most unusual inheritance. They may opt for $1 million or a clue leading to “the most important treasure in the world.” Some relatives take the money, but the rest choose the clue—including Amy and Dan. Tensions ramp up as family members pursue and threaten one another in the search for leads. Though the siblings aren’t as financially well off as many of their opponents, they have skills that give them an edge—Amy is a bookworm with a love of history, while Dan is a whiz with numbers and puzzles. The story remains faithful to the original 2008 book, with added smartphone appearances and a few scenes tightened up. The artwork captures the danger and excitement of the international quest, including locales such as Philadelphia and Paris. Backmatter includes an invitation to download Scholastic’s Home Base app so readers can be sorted into a branch of the Cahill family and play interactive games. Amy and Dan read White, while their au pair and adult chaperone, Nellie, is cued as Latine; the rest of the Cahill clan is racially diverse.

Wits and history expertise trump money and influence in this entertaining, globe-hopping remake.
