Working frantically to save their historic school from the wrecking ball scheduled in three weeks, sixth graders Ben Pratt and Jill Acton find the first of five safeguards planted more than 200 years earlier, an ally and treasure that may also help their cause. The story opens immediately after Ben has saved his arch enemy’s life, and readers will need to be familiar with We the Children (2010), the first in this planned six-volume series, to identify the characters and understand their relationships. Like that title, this is fast-paced and full of intriguing details ranging from clues leading to a hidden document and antique coins to the story of Horatio at the bridge and references to Jack London. Ben alternates between parents; in the first book he was living on his father's sailboat, so this week, he's home with his mother. Janitor Lyman continues to threaten, and even Jill seems nervous. The Massachusetts seaside setting takes a back seat to the increasing tension. Readers who’ve begun this well-written, modern kid-power mystery series will be glad to see this and eager for more.
