* Fear as Motivation: Isabel's constant fear for herself and her younger brother, Curzon, is a constant driving force. Her fear of being separated from him, of being sold, of being abused, pushes her to act. She's driven by the need to protect herself and him, even when it means taking risks.
* Fear as a Weapon: Isabel uses fear strategically. She exploits the fear of her owner, Mrs. Lockton, to gain some control over her situation. Her fear also becomes a weapon against others, allowing her to manipulate them and gain information.
* Facing Fear with Resilience: Isabel, despite the immense terror she faces, demonstrates remarkable resilience. She doesn't succumb to her fear but uses it as a source of strength. It allows her to make difficult choices, navigate dangerous situations, and ultimately fight for her freedom.
It's important to remember that bravery doesn't mean the absence of fear. It's about acting despite fear, and Isabel does this throughout the book. Her fear isn't her weakness, but her fuel. It's what makes her fight for a better future, even when all hope seems lost.
In summary: Isabel's fear is not what she overcomes, but what propels her forward. She doesn't rise above fear, but uses it to fuel her courage and resilience in the face of unimaginable hardship.
