When Callie McBride finds a woman’s phone number written on a scrap of paper her husband has thrown away, she thinks that her marriage is over. Callie flees to Nevada and her Aunt Nash’s Tamarosa Ranch, where she’s shocked to see that the place of so many happy childhood memories is in disrepair. Worse, Aunt Nash is acting bizarrely --- hoarding stacks of old photographs, burying a book in the yard, and railing against Kit Covey, a handsome government park ranger who piques Callie’s interest.
 
But Aunt Nash may prove to be saner than she seems once Callie pulls back the curtain on Tamarosa’s heyday --- the 1940s and ’50s, when high-society and Hollywood women ventured to the ranch for quickie divorces and found a unique sisterhood --- and uncovers a secret promise Nash made to her true love. Callie will come to see is that no life is ever ordinary. No story of love is, either.
