I thought I'd throw out some more images that I had in mind while writing "Dark Hunger" and the other Brethren books. For example, this is the Mercedes convertible that Rene loves so much. You'll find it in "Dark Thirst," as well as "Dark Hunger," even though in the latter, Lina is driving it, not Rene.
And this is the Audi sportscoupe that Rene and Tessa use to drive from Louisiana to Lake Tahoe in "Dark Hunger."
And Martin Davenant's Jaguar:
...which can indeed look sort of similar in shape and style to certain Hyundai models, as Rene discovers in the book...
