First thing, unlike in some series, this book does stand on its own. All of the story-lines are resolved and the teaser for what's to come suggests a ..Show More »new adversary too.
As for the content, I'm a massive vampire fan and this book both pleases and annoys me. It's great in how the reactions of the humans to the vampires are portrayed, they're a lot more realistic than a lot of vampire books. On the other hand, the vampires' ability to enter another (metaphysical) plane annoys me. As does the process for creating a new vampire.
The main romantic plot is also quite infuriating. The heroine is by turns easily manipulated and stubbornly intractable. It is rather difficult to see why the vampire would choose her over any other woman in history. That's not to say she doesn't have merits but there's nothing particularly incredible about her.
It is at times difficult to remember that this is meant to be set in the 20s, rather than the Edwardian or late Victorian period. The only bit that really convinces you of the setting is the heroine's sister in London. In fact, I think I could happily read a book all about her and her experiences with vampires. It would be more riveting.
