I feel a little torn over this, after all it is young adult orientated fiction and thus should I expect too much from it? After a little thought... frankly, yes, and that's where things fall down.
You see this is a book that has not too bad prose, a bit of a murder mystery and vampires but it does nothing really new for the vampire genre. The main character, Kira, is sixteen years old and only recently turned into a vampire so still has to go to high school - by order of her new vampire parents. You see the vampires in this masquerade as family units.
As such we know that sunlight is a minor issue (sunblock and a bit of a migraine are orders of the day). Strangely Summers went for the no reflection rule but at least stuck to the idea that clothes, makeup, hair dye etc would reflect offering an illusion of appearance on a casual glance. The invitation rule is in place but once more we get nice vampires, vampires without bite (well one has bite, but he or she is rogue).
We are introduced to a vampire hunter (who you can spot from a mile off) but nothing too interesting is done with him. The vampire parents are imposing (and the father can turn into a bat) but thinly drawn. One almost felt they were created with an eye on a subsequent TV programme, imposing but ultimately facile background characters. Kira herself came across as a younger (for you felt the age oozing out of the prose) version of Betsy Taylor from the Mary Janice Davidson series, but not as edgy or funny.
All in all this was a pleasant enough read but it didn't set my world alight, nor did it add anything particularly new or improved to the genre. Fine as it is, but average in the grand scheme of things.
