In this book the vampires have announced that they "walk amongst us" for a while. Seeing their gradual success and acceptance, werewolves have decided to out themselves in the hope of similar acceptance. The rest of the book follows what happens after their announcement. Is a local death the result of retaliation or something worse (a war between rival non-humans for example) going on?
The book isn't bad, but I don't think the series (at least in its' book form) is for me. It reads too much like chick-lit if I'm honest.
