Set in Boise, Idaho in the early 1980's, "Little Lost River" is the story of two young women who come together in the wake of tragedy. Cindy Morgan is still reeling from the loss of her mother when an accident leaves her boyfriend missing and presumed drowned. When Frances Rogers happens upon the accident site, she stays with Cindy until help arrives. In the aftermath of that night's events, as Cindy faces her future with a determination often misunderstood as indifference, Frances becomes her source of both support and compassion. Cindy and Frances are determined to find their own lives unencumbered by conventional expectations, but their path to adulthood is neither easy nor clear, and the future that each girl finds is not what she expected or planned. One generation follows another, and in the end the girls learn that life moves on its own path, that "transformation is what takes you forward. It's the only constant thing."
