Vixen - Naomi Swann - A Good Houseguest -hot Site

The "HOT" part is tricky. It could stand for many things. Maybe "House Of Thorns"? No, that's not related. How about "Heated Over Tension"? Unlikely. Alternatively, looking at the book covers and series, there's a common theme in some titles like "The Good Neighbors" series by Naomi Swann. But in this context, the HOT might be part of the title or a branding for a series or sub-series. Wait, maybe it's the name of the character in "Vixen"? Let me check.
