Now, what do you call that sorry state of affairs, eh?"
"Why, Jean-Luc!  It's what you Humans call "love."
 - Graziunas, Picard, and Q

Background information 
 Author Peter David's pitch for this novel was originally turned down by Pocket Books. When Pocket asked him to write Vendetta, David would only agree if this novel was also produced. After the finished manuscript was delivered in late , it went to Paramount for approval and editorial notes, but by , nothing had been received. With progress stalled, David decided to approach Majel Barrett Roddenberry at the I-Con convention in Long Island with the manuscript and seek her input into Lwaxana's character in the novel as a way of resolving the impasse. According to David, upon her return to the West Coast (having read the manuscript on the trip back), "she bustles into the Paramount office and proceeds to tell anyone who will listen about the book. Within two to three days after this happened, Pocket received four pages of comments." ()
Q and Lwaxana Troi appear in the same story.
 The audio adaptation sees John de Lancie and Majel Barrett Roddenberry take turns as narrator, voicing his or her own character, and dividing the remaining characters up by gender. 
 In another example of Shakespeare and Star Trek, two feuding houses are joined when offspring from each family fall in love. Romeo and Juliet is brought up for comparison, with Picard discussing the differences between the two stories.
