What is the author's tone in Benazir Bhutto: From Prison to Prime Minister by Libby Hughes?

The tone of Benazir Bhutto: From Prison to Prime Minister is appropriate for a pre-teen biography. Its tone is largely positive and tries to be inspiring. It becomes "sad" when things go poorly for Bhutto, but it hardly expresses the true tragedy of the execution of Bhutto's father, her brutal imprisonment and the harsh imposition of discrimination against women and military dictatorship by General Zia. The book, as a result, has a relatively simple, positive tone that is used to build up an inspiring and nearly saint-like portrait of Bhutto for her reader.
