Ages 9 to 12 years. The Zelnick family likes Christmas a lot, but Aldo -- whose plan to get presents galore may be running into a glitch -- does not. He thinks that "giving being better than receiving" is gobbledegook and doesn't understand what the "Adopt-a-Family Tree" at the mall has to do with him. Guinness World Records, holiday gnomes, a glass-blowing grandma, and generous helpings of goofiness abound in this seventh instalment in the series. A vocabulary-building glossary of fun and challenging words that start with the letter G, such as gumption, gloat, and gadzooks, is also featured.
