In "My Sister's Keeper" by Jodi Picoult, the idea of true love is depicted as a criminal act in an emotional sense. The quote suggests that love can be so intense and overwhelming that it leaves someone breathless, robbing them of their words and ability to express themselves. This highlights how love can profoundly affect individuals, making them feel vulnerable yet entirely captivated by another person.

The metaphor of stealing a heart emphasizes the deep connection and attachment that forms between people in love. It implies that such powerful emotions can transform one's life, creating a bond that feels almost illicit in its intensity. This resonates with the themes of the novel, exploring the complexities of relationships, sacrifice, and the moral dilemmas faced by the characters.
