After stumbling on this book through a friend, it took me less than a day and a half to read this thoroughly enjoyable easy read. Once drawn into the cleverly woven initial part of the book, i found it extremely hard to put down, as it flowed easily, and kept me interested throughout.
As someone who has read alot of this particular genre, i found that it appeals to people like myself who take an interest in some of the more historical context that the book is set in, and this context merges very naturally into the narrative of the novel. However, my sister also enjoyed the book, and she has little interest in history, or indeed a good book at all, highlighting the wide appeal of this book.
Once you get over the fact that vampires do not in fact exist, the book actually becomes quite plausible, and the author has quite cleverly worked facts in with fiction (and popular vampire myths), and characters that the reader can connect with, to give this novel a feeling of believability that i did not actually expect, considering it is about vampires flying spitfires and mosquitoes in WW2.
Although this book would make a very good read for teenagers, i also completely recommend it to the more mature reader, especially as an easy read for a slow day in the office or similar circumstances.
