Ever since her husband Bruce died from pancreatic cancer, 32-year-old Holly Brennan has holed up in their suburban dream home, paralyzed by sadness and gaining weight from too much grief-eating. When she has to go out of town to settle his estate, fate strikes. Because sitting next to her on the plane home is Logan Montgomery, a personal trainer to the country's most famous pro athletes. After a bumpy take-off, Logan discovers that the seatmate he'd thoughtlessly written off as just another fat chick has a sharp wit and keen insight. Intrigued, he makes her an offer: he'll train her at his state-of-the-art gym and help her get back into fighting shape at a special reduced price.
When Logan introduces a more slimmed-down Holly to his best friends, they instantly see what Logan doesn't; Holly is a bona-fide looker. But can a man who's spent his whole life hung up on looks -- his own and his clients' -- truly commit himself to a woman who's not supermodel-thin? Now that Holly's fit and turning other men's heads, does she even need Logan anymore? Are they built to last or is their sizzling affair just one of those ill-advised client-trainer romances?
