The Heffley family's house undergoes a disastrous attempt at home improvement.When Great Aunt Reba dies, she leaves some money to the family. Greg's mom calls a family meeting to determine what to do with their share, proposing home improvements and then overruling the family's cartoonish wish lists and instead pushing for an addition to the kitchen. Before bringing in the construction crew, the Heffleys attempt to do minor maintenance and repairs themselvesduring which Greg fails at the work in various slapstick scenes. Once the professionals are brought in, the problems keep getting worse: angry neighbors, terrifying problems in walls, andmost seriouscivil permitting issues that put the kibosh on what work's been done. Left with only enough inheritance to patch and repair the exterior of the houseand with the school's dismal standardized test scores as a final strawGreg's mom steers the family toward moving, opening up house-hunting and house-selling storylines (and devastating loyal Rowley, who doesn't want to lose his best friend). While Greg's positive about the move, he's not completely uncaring about Rowley's action. (And of course, Greg himself is not as unaffected as he wishes.) The gags include effectively placed callbacks to seemingly incidental events (the "stress lizard" brought in on testing day is particularly funny) and a lampoon of after-school-special-style problem books. Just when it seems that the Heffleys really will move, a new sequence of chaotic trouble and property destruction heralds a return to the status quo. Whew.Readers can still rely on this series to bring laughs. (Graphic/fiction hybrid. 8-12) Copyright Kirkus Reviews, used with permission.
