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 the first of July in 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.
