Two of a Kind Diaries

Forty short novels published by HarperEntertainment between December 1998 and April 2005, launched as a tie-in to the ABC sitcom Two of a Kind, which starred Mary-Kate and Ashley Olsen as twin sisters, and continuing for years after the show itself ended. Each book is written as the sisters' own diary entries, covering school, friendships, crushes, holidays, family trips and summer camp. The covers credit Mary-Kate and Ashley Olsen, but the books were written by a rotating group of authors including Judy Katschke, Megan Stine, Nancy Butcher, Diana G. Gallagher, Louise Gikow and Lisa Banim. Written for young readers, and readable in any order.
