Just Patty by WEBSTER, Jean

Patty, Conny, and Priscilla are the best of friends, and roommates at boarding school. While the teachers might say they are mischievous, even troublemakers, Patty and her friends act only in accordance with their convictions. From forming a labor union to furnishing a house for the neighbors, Pattys ideas are unconventional, yet loads of fun. Just Patty is the prequel to When Patty Went to College, the first novel by the author of Daddy-Long-Legs and Dear Enemy.(Summary by Lorelle Anderson)
