Incomplete question. However, I inferred you are referring to the book "Malala, a Brave Girl from Pakistan/Iqbal, a Brave Boy from Pakistan: Two Stories of Bravery."
Step-by-step explanation:
Remember, a metaphor is a figure of speech (a word or phrase that does not have a literal definition) rather the meaning is symbolic in nature.
Malala’s kite metaphor tells us her strong belief to attain true freedom to receive an education. According to the author, Malala's holding a firm grasp on her kite string shows her fight for freedom in an environment that despises female education.
