In the wake of a freak storm, something is rotten in the town of Greenfield.Jessie Alden is eager to dive into the new school year: new classes, new friends, new clubs, and, most importantly, new Jessie. That means leaving behind the old Jessie, who "hung out in a boxcar and solved mysteries" with her siblings. But when a new boy at school approaches her with a tale of a bizarre transaction at his parents' art store and strange occurrences in her neighborhood pile up without adding up, Jessie just might have to don her investigator's hat once again, this time with her friends by her side. Deutsch has given the Boxcar Children franchise a modern twist but retains salient features of Gertrude Chandler Warner's original series in creating her version of Greenfield. In doing away with the original family investigative team, this opener heralds a series that feels closer to the A-to-Z Mysteries by Ron Roy and John Steven Gurney, similarly suffused with red herrings, small-town sensibility, and unexpected antagonists, with the added overarching theme of the power of friendship. Characters are distinct and likable, if somewhat shallowly developed, and the surprisingly mature plot clips along at a spritely pace. Jessie and her family are presumed White; supporting characters are children of color.A case worth cracking. (Fiction. 9-12)
