Forever Dawn by B.D. Schmidt
preface
Kadi and Taylor were vampyres, and not just regular ones like in Dracula and all of those other stories, but a special brand. A brand so rare, they were thought to be extinct. The reason their brand of vampire was so rare is because of the bond they share. When Taylor was 15, she was a victim in a terrible car crash that killed her and her dad. The two were in his new sports car, with the 18 year old Kadi in the car behind them, following along, when it happened, causing K to witness everything. The two were hit by a drunk driver and killed instantly.
The second they crashed, Kadi used her speed to get out of her car and drag the closest person out of the car. Kadi was already a vampyre and had inherited a power from her unknown creator to heal people. When she pulled Taylor out she had already been dead, but that didn't stop her from attempting her healing abilities on a dead body. A very hysterical, bawling Kadi tried to heal Taylor for 3 minutes, and right when she started to give up, she heard the most amazing sound she had ever heard in her life. A breath. Taylor started gasping for breath and coughing up blood. She was alive.
There was an odd side effect of the revival though. It was the side effect that would keep them linked together forever. Taylor has a sort of tracker that lets her know where Kadi is at all times and if she's okay. Only Kadi though, can read Taylor's mind. They can both send messages to each other like they are in the same room, even though it looks like you're talking to yourself, too. So here they are, blood sucking vampyres and bonded more than any sister would ever want to be bonded with a sibling.
