The family division opens. Brothers, sisters, new babies, technology, teamwork, and Dewey's own increasingly complicated home life all end up in the file.
OPEN FILE →WHO IS THIS FOR?
The series project materials identify the books for ages 9–12 and grades 4–7, while Lorri's Book 1 curriculum guide specifically supports grades 3–5 and older struggling readers. That makes Dewey useful for independent readers, family reading, classroom discussion, and readers who respond to humor and highly concrete problems.
OFFICE DIRECTORY
Dewey does not operate alone. Clara keeps the office moving, Wolfie occupies the canine department, and Seraphina and Colin keep showing up whenever the case gets complicated.
THE FILE HAS HISTORY
Parent Problem Solver received a starred Kirkus review and was included among Kirkus' Best Middle-Grade Books of 2017. Publisher materials also positioned the series beside titles such as Spy School, Lunch Money, Encyclopedia Brown, and other humorous problem-solving or school-centered books. Those are historical publisher comparisons—not claims that the books are identical.
