In "Vixen," the main characters are Rhett and his wife Vixen. There's also a book called "A Good Houseguest" which is part of the Good Neighbors series. Maybe the HOT is another book or part of the same series. Alternatively, "HOT" could be part of the title if there's a book called "Hot Neighbor," but I'm not sure. Alternatively, looking at the covers and blurbs, the author might have a series called "The Good Neighbors" where each book's title is a phrase, and HOT is part of it. Or maybe the user is looking for a connection between these titles and the acronym HOT itself.
Starting with "Naomi Swann" - She's an author, right? I think she's written some books, maybe in the romance genre? I'm not exactly sure but I recall something about a book called "The Perfect Neighbor" which might be hers. Also, there's a book titled "A Good Houseguest" and "The Neighbor" which are part of her series. So, Naomi Swann is the author here. Vixen - Naomi Swann - A Good Houseguest -HOT
Alternatively, maybe the user made a typo and HOT is supposed to be another book title. I remember that there's a book called "The Good Houseguest" and then "The Perfect Neighbors." So maybe HOT corresponds to another one. Or perhaps HOT is part of the book cover's tagline or something similar. In "Vixen," the main characters are Rhett and his wife Vixen
