how did sookan change from the beginning of the book to the end of the book?

Sookan goes from a girl full of fear to a seemingly fearless young woman who never gives up. She does what she can to sabotage Japanese efforts to crush the Korean spirit, and when she is upset, she tries to picture Buddha so that she can channel her Grandfather's wisdom and joy. Sookan shows that she is very strong and brave when she and Inchun make it safely across the border out of North Korea. She has to act as a sort of surrogate mother to Inchun, but she tries to find ways to look on the bright side and be resourceful.
