Gayle Forman's inspiration for Just One Day came to her in a dream. In her dream, she dreamt about a guy and a girl who were in a warehouse. The guy and girl were abroad, and she knew that they shared a very intense day together. When she woke up she started to write the story. In the book, Willem is inspired by a Dutch guy that Forman dated. Foreman is best known for her popular 2009 young adult novel, If I Stay, she also published a fiction trilogy that consisted of the titles Just One Day, Just One Year, and Just One Night. She was also a journalist, she for Glamour, Elle, Cosmopolitan, and other publications. Foreman's literary honors are the ALA/YALSA Quick Pick for Reluctant Young Readers Award and the 2010 British Fantasy Award. Forman and her husband, live in New York and have one biological daughter and one adopted daughter. I think Forman chose Allyson as the character to reflect herself because Allyson finds her true self. She is very determined and headstrong. Allyson and Foreman both enjoy traveling. They are successful, Foreman has many literary honors including, ALA/YALSA Quick Pick for Reluctant Young Readers Award and the 2010 British Fantasy Award. Allyson is successful in college when she decides to choose her own classes and path.
