Mix Breed (Book 1 of the Tiaksana series)
"We don't always agree on much, but there is one rule we all agree must never be broken. Never fall in love out of your own kind. If you do, you and anybody who knew about it and kept it secret disappear. This rule has been drummed into me from the day I was born. It's the most important thing I've ever learnt because it is the one rule that is closest to my heart. My mother is a vampire, but the secret that only she and I share, is that my father was a werewolf.
My name is Tia, I'm a mix breed. And if anyone ever finds out, I'm dead."
