Mikes younger sister, Abby, is inquisitive and brave, with a creative mind and keen intuition. A bit of a loner who keeps her thoughts and feelings close to her chest, she expresses herself primarily through drawings. Growing up without her parents, while being raised by her unreliable brother, Abby has learned to fend for herself. That said, she is still very much a child, emotionally vulnerable, full of imagination, and not without the normal outbursts of a 10-year old.
