The series is split into a number of trilogies. This is book #1 of the second trilogy (The Vampire Rites Trilogy (USA.))
This book can be read as standalone, should you wish, though it clearly leaves room for the book after it, and does make reference to the events of previous books.
This is a kids book - probably suitable for age 11+ - but obviously, age shouldn't be a barrier if the kid is mature and/or capable of reading to this level.
And, of course, this book is suitable for adults who refuse to be bound by the restrictions of age (like me!)
The story is interesting - which is always a plus. This alone may be enough to tempt even a reluctant reader through the chapters (which are fairly quick and pacey.)
The dynamic between Darren and the world he now inhabits is well portrayed - with particular room for expansion in the relationship between Darren and Mr Crepsley.
I also like the female vampire Arra Sails, because she's pretty damned cool. And I love the challenges Darren faces as a slow-aging kid-vampire - it adds an extra dimension of feeling older than the world perceives you to be.
What I object to, though, is the treatment of the old, the infirm, and the 'mad,' vampires - politically correct this is not; euthanasia is not a topic which should be treated in a manner that's quite this blasé, and almost cold. This isn't integral to the book as a whole - it's more of a side-detail - but it p**sed me off.
