Twins

Kayla or Kay, for short, and Katelyn or Kate, for short, are identical twins. They seem alike at first, but they have one big difference.
The difference is simply just the fact that Katelyn is a Werewolf, and Kayla is a Vampire.
They were always together, and could never be torn apart, but when they go to a school for mystical creatures, where their kinds are torn apart, and are at war, like they have been for the last one hundred years. Will their strong bond be able to survive or will they be torn apart?
