Abbie Richardson is a character the Sweet Valley High books.
She makes her first appearance in SVH #44 Pretenses. She was described as having been once a close friend of Jessica Wakefield and Lila Fowler, but however, when she began dating a young man from Big Mesa High School, she dropped off the SVH radar. When they broke up, Abbie became more prominent.
She was a talented cartoonist and was planning on submitting her cartoon called Jenny to the paper. She was up against the snotty Amy Sutton who was wanting to put a dating advice column in The Oracle. She slightly ran afoul of Cara Walker when she thought that she was interested in Steven Wakefield. However, she wasn't, and was more into her art.
Happily, she won the Oracle contest and became the paper's new staff cartoonist, and she became one of Elizabeth Wakefield's friends. Abbie was rare in that she was one of the few characters who were friends of both twins at one point or another.
