Once Is Not Enough is a mantra Jackie always knew. It's also the title of her 1973 bestseller about a young woman trying to find love in the jungle that is New York City. January Wayne goes from poor-little-rich-girl to tragic heroine, as she searches New York and Los Angeles for a man just like her father, Mike Wayne, a glamorous movie producer. Unfortunately for January, no man ever measures up. As January works her way up Manhattan's magazine world, she gets hooked on vitamin shots and Tom Colt, a literary star with a larger-than-life personality, a giant appetite for booze and, sadly for January, an "ailment" that was a priceless example of literary revenge.
