Our Worlds

I DO NOT OWN TWILIGHT! THXS!
"Edward. We can't. Our worlds are too...different..." I try my best to explain to Edward, but he just wouldn't understand.
"Why? What's so different?" He begs back, with pain evident in his eyes. I have my reasons for doing this but I know. I just know. He is not my blood bond. And I am not his mate.
"Because I'm a Coffin Riser, Edward. You're a Cold one. Our world just don't mix, they're too dangerous. To...wrong."

What if cold ones weren't the only type of vampire? What if there was another type of stronger, better vampires that go by the name of Coffin Risers?
A heartbroken, soul shattered Bella meets the new kids in school. The Kenzies, but they aren't normal either. The Kenzies end up family bonding with Bella and they have no choice but to change her in order to let her survive. Bella learns about how to feed from animals and to control her powers and such but what happens when the Cullens come back to town only to find Bella is not Edwards mate?! Then who does Bella belong too?
