Trial by Fire - Danielle Steel

In this inspiring novel from #1 New York Times bestselling author Danielle Steel, the life of a Parisian woman changes in a heartbeat when she's trapped by wildfires in Napa Valley.
Born to a French mother and American father, graceful Dahlia de Beaumont has been sole owner and CEO of the venerable family perfume business based in Paris since her early twenties, following the death of her parents. For twenty-five years, after losing her young skier husband in an avalanche, her life has centered on running Lambert Perfumes and being a devoted single mother to her four now-adult children: indecisive Charles, volatile Alexa, kind-hearted business visionary Delphine, and dreamy artist Emma. Now fifty-six, she has an "arrangement" with a married French man but has been questioning that relationship.
Dahlia comes to San Francisco on a routine business trip to check on her stores in the States. But shortly after her arrival, brush fires ignite in Napa Valley. Watching the sweeping devastation on the news, Dahlia is moved to help. But doing so will bring unforeseen consequences that endanger not only her life, but her entire future. Forced to remain in San Francisco in the aftermath, she will make unexpected connections while also fighting to protect all she has worked for. What Dahlia learns will provide a new perspective of her life, forever changing what really matters to her and what comes next for her journey.
With this uplifting novel, Danielle Steel beautifully dramatizes how life's unforeseen challenges can sow the seeds for growth and a fresh chance at love—if one is willing to take the risk.
