What is the author's tone in The Boy Who Harnessed the Wind: Creating Currents of Electricity and Hope by William Kamkwamba?

The overall tone of the book is one of its more interesting aspects. On the one hand, it is almost entirely subjective, in that it is written entirely from the point of view of its central figure, narrator William. Stories of other persons (i.e. William's father) are included, but are referred to in William's terms - as he heard them, discussed them, and understood them. This draws the reader closely, intimately, and thoroughly into William's story and experience. But perhaps somewhat surprisingly, there is a certain sense of objectivity about the narrative as well, a certain sense of emotional distance. The reader is easily able to appreciate both William's achievement and his struggles, but doesn't necessarily or easily celebrate with him when his dreams are realized (i.e. when the light bulb illuminates during the windmill test in Chapter 11). In some ways, the narrative is almost journalistic in its approach, describing the emotions triggered by circumstances without necessarily opening those emotions to the empathy of the reader.
