Perfect Little Monsters

Moderately interesting twist ending I won't spoil, but so many of the details of Dawn's attempt to investigate were predictable and “revealed” in an obvious way. Even the twist isn't a surprise and is there for shock value that just isn't actually there - but perhaps it's not meant for mystery/thriller fans? (Or anyone past teen years, considering the ridiculous throw-in lines emphasizing “Isaac's car is so ancient, it takes a key to start it, not a button” but no mockery of it having a CD player.) 

I did enjoy it, it's a decent first book, but it's oddly hollow. I might read more from this author but probably not anything else featuring teen characters.
