From School Library Journal Grade 5-8-Between 1890 and 1903, whole forests of giant sequoia trees were felled for lumber in northern California. In this exciting adventure story, Francie, 15, begins to unravel a mystery when she finds a hidden note left by her sister, now deceased, in the hole of a tree and sets out to stop the logging of the biggest giant. Set in 1894, the novel is a fast read, ending with a daredevil ride on the loggers' flume. Francie is a brave, high-spirited teen who values commitment, history, the environment, and the legacy of her sister's memory. A subplot involves the family dealing with the loss of Carrie six years earlier. The uneasy decision between whether to save the tree in memory of Carrie or save the economy and the loggers' jobs is handled objectively. Pfitsch has researched her subject well and gives the California mountain landscape and its inhabitants a note of realism. However, the book is weakened by too simple a resolution, the downplaying of natural hazards in the wild, and many dangers either glossed over or omitted. The writing is sometimes repetitious, but it is easy, making the story an accessible and enjoyable read. Some moral-value issues, such as telling the truth and minding parents, are nicely handled. The attractive jacket depicting the dangerous ride on the flume should draw readers and help sell the book.
