The Imaginary Girlfriend is a terrific memoir. Irving, while taking a break from writing novels, decided to pen a short autobiography, but he brought his usual sense of humor, ability to develop characters, and readable style to the project. The story does an excellent job of explaining the life events and people who have shaped his character and writing, which I think is very useful when trying to understand and appreciate his other books. I think this story itself is some of Irving's best writing and is certainly worth the short time it takes to read. I would recommend, however, instead of paying for the memoir alone, you purchase Trying to Save Piggy Sneed which includes this memoir as well as several short stories. You will not be disappointed if you are an Irving fan or just enjoy good, entertaining writing.
