Sweet Valley Twins (also known as Sweet Valley Twins and Friends) was the first spin-off to originate from Sweet Valley High, and was created by Francine Pascal and written by Jamie Suzanne. Published by Bantam Books on 1 July 1986, the series starts with the twins wanting to differ from each other. They begin to dress differently; Elizabeth moves into her own room and starts up a sixth-grade newspaper; and Jessica starts wearing make-up and becomes a member of the Unicorn Club.
