NEW YORK TIMES BESTSELLERJillian Westfield has a life straight out of the women’s magazines she obsessively reads. She’s got the modern-print rugs of Metropolitan Home, the elegant meals from Gourmet, and the clutter-free closets out of Real Simple. With her investment-banker husband behind the wheel and her cherubic eighteen-month-old in the backseat, hers could be the family in the magazines’ Range Rover ads.Yet somehow all of the how-to magazine stories in the world can’t seem to fix her faltering marriage or stop her from asking "What if?"Then one morning Jillian wakes up seven years in the past. She’s back in her Manhattan apartment. She’s back in her fast-paced job. And she’s still with Jackson, the ex-boyfriend, and star of her what-if fantasies.Armed with twenty-twenty hindsight, she’s free to choose all over again. She can reconnect to the mother who abandoned her, she can use ad campaigns from her future to wow her clients, and she can fix the fights that doomed her relationship with Jackson.Or can she?
