Life is crazier than ever for the squabbling siblings when younger sister Maureen winds up in a leg cast! But that doesn't prevent her from perpetually pranking her sister, Wendy.  At least until Wendy sees her boyfriend with her best friend, Sammie.  Can Maureen console her heartbroken sister?

"This book is based on the wildly successful series originally published in France, and THE SISTERS have lost none of their exuberant charm in this English translation." -- School Library Journal
