The aroma of freshly brewed coffee filled the small apartment, a familiar comfort to Clara. She twirled a strand of her auburn hair around her finger, listening to the lively chatter coming from the café downstairs. Today was going to be a good day, she just knew it. She had secured a new client and was excited about the project.

A courier arrived, holding a large box. "Clara Bellweather?" She confirmed her name and signed. Inside, nestled amongst packing peanuts, was a book. The cover announced *Clara Bellweather: A Portrait of Resilience*. Her stomach did a little flip. She opened it, discovering detailed accounts of her family history, her struggles with starting her own business and how she had overcome adversity to get where she was now. A warmth spread through her chest.
