Before the very end of season 5 of the show, Diane gets the chance to finish a long-term project, a book she started writing years ago. What was the name of that book?

It's revealed in the final episode of that seasons, Diane's last, that her book "Jocasta's Conundrum" will be published, an achievement only made possible by none other than Sumner Sloan, the very fiance that left her in the first episode, leading to her taking a job at the bar.
