Published by Bantam Books on 1 July 1986, the series starts with the twins wanting to differ from each other.
She enjoys reading (her favorite books are Amanda Howard mysteries) and writing, and hopes to become a journalist someday.
Jessica Wakefield is the complete opposite of her twin; she loves gossip, boys, and fashion.
Elizabeth, Maria, and a sixth grader named Evie become Unicorns too, and they all volunteer at the day care center.
When Kimberly moves back, things change, and Elizabeth, Maria, Evie and Mary leave the Unicorns and start a new club called the Angels.
