Persephone "Persi" Sinclair has always lived a principled and disciplined life—with one exception. She's in love with a married man. She can't help herself; she's had a crush on Brad Shelton since high school. When Brad finally dumps her to rekindle things with his wife, Persi gathers her shattered pride, dusts off her old dreams, and moves to Paris. Persi reconnects with Nick Betancourt, a former college classmate of Brad's who's playing saxophone at Bricktop's Jazz Club. Reluctantly, Persi begins to date the free-spirited Nick, and is slowly seduced by his charm. What begins as a carefree adventure through the French countryside with no past, no future, and no designs on permanence, turns into something much deeper. The couple gets married in Monte Carlo and returns to their Paris flat. Persi settles into the role of Mrs. Nick Betancourt and deems herself fulfilled, content, and happy—until Brad shows up at their front door one day, announcing that he's left his wife for good. The decision is Persi's. Does she return to her former lover, who is finally offering marriage, or does she remain with her husband and see where their newfound love leads?
