Carole wrote several magazine articles about her experiences during the war. In 1943 she was asked to write a book for Random House. The title of the book was Four Jills In A Jeep. She told stories about traveling with the other women and performing for the soldiers. Most of the book is about her romance with her husband Tommy Wallace. Carole had the help of a ghostwriter named Edwin Seaver but she wrote the majority of the book herself. She dedicated it "To the Officers and Enlisted Men Who Made Our Tour So Inspiring". In December 1943 Four Jills In a Jeep was serialized in The Saturday Evening Post. When the book was published in the spring of 1944 it sold well and got rave reviews. Before the book had even come out Fox decided to turn Four Jills In A Jeep into a movie. Filming began on October 18, 1943. The movie was directed by William A. Seiter.
Unfortunately Carole and the other actresses had no creative control over the making of Four Jills In A Jeep. The movie ended up being mostly fiction. The plot made their journey seem easy and it completely ignored all of the struggles they went through. Many of the scenes and characters in the movie did not even come from the book. Carole was very unhappy that it turned out to be just a fluffy musical. Four Jills In A Jeep was released on March 17, 1944. The movie was not a hit and a lot of critics panned it. Carole told a friend "I'm afraid the picture hasn't had as good a press as I hoped". Although she had proved she was a talented writer Carole would never write another book.
