I have the Barlowe, Bledsoe and Monette/Bear books on my shelf, all only available in hardcover editions sofar. I've read the first and last one and I'd say the last one is worth reading. People will undoubtedly complain about not keeping the many similar names straight and there will be commentary about the graphic nature of the sex, as well what sort of sex it is. But it's got a cool northern setting and a nice plot.
The Barlowe book is very good, very cool Heaven and Hell story.
