Book excerpt: The bestselling star of No, David! turns Christmas traditions upside down with laugh-aloud humor. Readers of all ages will vividly remember trying to peek at hidden gift packages; writing scrolls of wish lists to Santa; and struggling to behave at formal Christmas dinner parties. Always in the background, we know Santa Claus is watching, soon to decide if David deserves a shiny new fire truck or a lump of coal under the tree. From playing with delicate ornaments to standing in an endlessly long line for Santa, here are common Christmas activities--but with David's naughty trimmings. A surefire hit that is destined to be an annual classic.
