I am an unashamed Twilight nut, and I absolutely loved this. In fact Edward Cullen and Alexandre (from Hidden) are toughing it out for top spot on my bookshelf as i am writing this. It's beautiful, dark and richly gothic, and dead creepy too. It's got everything a teen would love (I'm not a teen by the way) leaving home for the first time, romantic old mansions in the country, pretty vamps and a truly creepy ancient city of underground vampires. And, most important, a cracking story.
If you have a Twi-shaped hole in your life, this will more than fill it. Can't wait for the next one in the series.
