If you’ve got the other Mallory books in your library and you’ve got students who are fans, go ahead and get this one, too, but as a stand-alone book I wouldn’t bother. It tells the story of ten-year-old Mallory planning a sleepover, trying to balance her best friend’s vision of the party to end all parties and her parents’ instructions to keep things small and quiet. Not surprisingly, a whole series of things go wrong as the party spirals out of control, and the book ends with Mallory acknowledging where she made bad choices, apologizing to injured parties, and promising to be wiser in the future. The girls’ problems were believable and predictable. My biggest gripe with the book was the behavior of the parents: the book focuses on all Mallory should have done to avoid the problems, but to me the failings of the parents were much more obvious — as adults they should have been able to foresee the possible problems and been involved. The book lays way too much of the blame for what happened at Mallory’s feet, instead of holding the idiotic parents responsible.
