After a movie deal in September, Jessica Walsh and Timothy Goodman of 40 Days of Dating have now landed a book deal with Abrams for their project.

The book, which is scheduled for release in fall 2014, will include "texts, conversations, artwork, photographs, and details of the romance before, during and after the experiment."

Creative Artists Agency, which represents Goodman and Walsh, negotiated the deal with adult trade publisher Deborah Anderson.

Earlier this year, Enstars had interviewed Walsh about which form -- film, television, or book -- she felt was best for an adaptation of the project.

"A book will provide a great format to expand upon what happened during the 40 days, but also give insight into what happened after," she said.

Walsh also told Enstars about her favorite book, Le Petit Prince, by French writer and poet Antoine de Saint-Exupéry. Suggesting that she related to it most when it came to associating with a character and romantic relationships.

In September, it was announced that the project had been picked up by Warner Bros. for a film adaptation.

Michael Sucsy (The Vow, Grey Gardens) will direct the film and Lorene Scafaria (Nick and Norah's Endless Playlist, Seeking a Friend for the End of the World) will pen the script. Michael Sugar, Joy Gorman and Bard Dorros will produce for Anonymous Content and Ashley Zalta will be a co-producer. Anonymous Content manages the director and scribe. 

Walsh and Goodman started the experiment to explore what it took to make a relationship work in New York and if good friends could make for good lovers. Both Manhattanites struggled in past relationships and decided to see each other for 40 days, going on at least three dates a week and having strict rules for their relationship. The couple filled out a daily questionnaire, visited a couple's therapist once a week and promised not to date or have sex with anyone else. They documented everyday of this trial period and fans could follow their relationship on their website. The project ended with the couple parting ways.
