This is not your average vampire book. It definitely has some plot elements that are unique to this author. It was quite enjoyable; what kept me from giving it five stars is the lack of proofreading and copy-editing.
Let's see, BunRab's usual analysis of vampire books:
Is it part of a series? It claims to be the first one in a series; the back page says that Book Two is "coming soon."
What's the author's main genre? I haven't read anything else by this author; she doesn't, as far as I know, write any other types of fantasy or science fiction, nor murder mysteries, nor in the romance genres. This book has some romance features in it, but is definitely not a romance per se.
Vampire powers: Does daylight kill these vampires? Direct sunlight does; indirect (e.g., being awake but inside during the day) doesn't. Do the vampires have any supernatural powers? The usual ones of supernatural strength, and being able to make people not see them. Also, telepathy occurs in most of them. In addition, they have the power to create "thralls," humans who have tasted some of their blood and are therefore longer-lived and faster-healing than other humans. Oh, and they can also enthrall dogs!
Do the vampires need to drink blood? Does it have to be human? Yes, and yes. Most lines of vampires exist only on blood, and need to feed every day, therefore; the line of vampires, or clan or family, whatever you want to call it, that are our main characters are unusual in that they can still eat regular food, and can get up to 2/3 of their sustenance from regular food, needing only about 1/3 of their intake to be blood.
Does drinking the blood have to do with sex? Are vampires a metaphor for humanity's sexual fears? Yes, and no. Drinking blood can involve sex, and apparently is better for the vampires if it does, but they can feed without it, and can leave the humans not remembering that they were fed on. Vampires actually have personalities of their own, and are not merely dark, brooding and evil- although some other families than our heroes' do seem to specialize in evil and death, it isn't a requirement for being a vampire.
The book is not deadly serious (pardon the pun) but has several touches of humor. There are sibling squabbles and long-standing family jokes, there are amusing moments in the Pagan shop that Paul and Marcie run; even a few of the vampires and thralls have senses of humor. The tone is not entirely different from Laurell Hamilton's earlier books, before they turned entirely to sex. There are serious and deadly moments, but also light-hearted ones.
Now, if only someone would run off a second edition, in which the lack of commas in many places got fixed, while some of the run-on sentences with too many commas got turned into separate sentences, or at least had a few semi-colons added, and if the occasional use of "hadn't of" were fixed, and the kind of word substitutions that spell-check doesn't catch (too for to, it's for its, and so forth) were corrected by a human proofreader (or a vampire one, for that matter- just not a computer one!) I would be even more satisfied with the book.
