Dinner With a Vampire is a great opening to what is bound to be an exciting new series. I was truly engrossed in the story, in love with the characters, and dying to see what would happen next. I did have two (and a half) issues with this book, however.
1) The story is supposedly told in two different perspectives, which, in general, I love. It's nice to throw a bit of dramatic irony into a novel, mostly for the enjoyment of the reader, but this book failed in a major way - for me, at least. Approximately 90% of the book is written from Violet's perspective. As much as I loved her, I also loved Kaspar's chapters, which were, unfortunately, around only four pages each. It was very disappointing, in my opinion. I hope that the next book (if told in the same way) strikes more of a balance between the two main characters. Kaspar is likable, after all... I would just have liked to read a little bit more about him.
2) The second half of the book seemed to follow a completely different plot to the first half. Both halves were great, sure, but extremely different. For example, Fabian is a prominent character in the first half. I grew to like him a lot, to the point where he was basically my favourite character. But then he isn't in the second half at all; I don't think he even has one line. It was almost like the second half of the book was written as a sequel, as the plot (and Kaspar's attitude) completely changed.
.5) There were numerous typos/words-that-should-not-be-there throughout the book. It doesn't bother me TOO much, but I do feel that these should have been screened out in the editing process. Nevertheless, it was still readable, and I enjoyed it thoroughly.
Excluding the above, this book would definitely be on my favourites shelf. It had action, romance, mystery, suspense, and (although Violet was annoying sometimes) I will be buying the sequel. This book sort of makes vampire books seem "cool" again (shock, horror!).
