What metaphors are used in Benazir Bhutto: From Prison to Prime Minister by Libby Hughes?

Percecution is a metaphor through the book. Despite Bhutto's elite upbringing, she was no mere child of privilege. No one doubted that her political beliefs were strong, honest and serious from her political awakening at Harvard. And despite the training given to her by her father and his pressure to place her in excellent Western Universities, she developed a genuine passion to aid her country. If anyone doubts her commitment, her willingness to endure imprisonment should count as significant counterevidence.
