Set in 1894 and based on a history of the logging projects among the California sequoias, this is a story of Francie, whose sister died in an accident six years earlier. She chafes under her parents' excessive protectiveness since Carrie's death. She loves the woods, and longs to do something to keep the loggers from cutting down the ancient sequoias, especially the oldest and largest, a tree over 2500 years old. Through a little sleuthing based on her sister's diary, she finds out that the property on which the ancient tree sits actually belongs to an old hermit, not to the logging company.
In an effort to get the company to stop before cutting the oldest tree, she rides the dangerous log flume into town to alert the one journalist she knows will support her cause. They arrive in time to save that tree and some of the others, and, perhaps as importantly to Francie, her mother and father begin to see her not only in terms of their loss of Carrie, but as a young woman independently interesting, daring, and very much alive.
