The One That Got Away by Leigh Himes
Abbey Lahey is a married, harried working mother of two, struggling to make ends meet in a blue-collar suburb of Philadelphia. When a freak tumble down a Nordstrom escalator lands her in an alternate reality, Abbey finds herself happily married to the one who got away-a dashing Philly blueblood she met briefly years earlier-and living a Cinderella life of privilege and luxury.
It's everything Abbey ever dreamed of... or is it? At first dazzled by the clothes, the penthouse, the nannies, and the glittering social functions, Abbey soon begins noticing troubling flaws in her new fourteen-carat life. And, all the while, she wonders about the people she left behind. Torn between two vastly different realities, Abbey takes increasingly dramatic steps to reclaim herself---whoever that may be.
