Hillary is a 5th-grader who lives with her mother, father and younger brother Chef. Her best friend Zoe, along with Chef's best friend, Tek make up this lively foursome. While each of the children have something special that they bring to the group; Chef's interest in the culinary arts, Zoe's love for theater and dance, and Tek's need for high tech gadgets, it is Hillary's talent for all things entrepreneurial that steals the show in this first book. The first of this three-book financial series highlights Hillary's ability to create a business opportunity that enables her to earn the funds she needs to purchase a new bicycle. Her spunky attitude and great determination leaves the young reader excited to see what Hillary and her crew come up with next, and if they achieve their goal. At the end of the story, there is a lessons learned section, which features new vocabulary terms and a fun team project for children to work on with their parents, or at school with their teachers.

Hillary's BIG Business Adventure is Nelson's first published work. While in graduate school, Nelson worked as an elementary substitute teacher in Maryland. It was during this time that she realized her desire to reach African-American youth. She enjoys portraying young African-American children as lead characters experiencing and successfully overcoming conflict and the challenges of being young in today's not so "kid-friendlyö society.
