Thirteen years ago, one of Daisy Tucker's 3-year-old twins, Jake, disappeared during a cattle roundup at the family ranch in Wyoming--an event that disrupted her marriage to her husband, James. Since then, Daisy has lived with Jake's sister Sage, now 16, in New England, where her own family is from. Now Sage goes back to her father, taking along her boyfriend and the news that she's pregnant.
