The Hatford boys’ New Year’s resolution is the girls can stay … but only if they play by our rules. Their mother insists that they treat those girls as though they were your sisters. Okay, but somehow the boys’ interpretation owes more to sibling rivalry than to brotherly love. The one weak link is young Peter, who doesn’t understand the rivalry, openly likes the girls, and sees nothing wrong with sitting in their kitchen eating homemade cookies and answering questions about his brothers’ plans. Readers will find themselves laughing out loud at the pranks, the conversations, and one unforgettably embarrassing moment. The high-flying humor is juxtaposed with the budding affection between Josh and Beth and the way all the children pull together during a blizzard. The fifth entry in Naylor’s refreshing series chronicling the feud between the Hatfords and the Malloys.
