The Vampire's Kiss

One kiss to change both of their lives forever...
Brenna is on a mission. She wants to fulfill the prophecy a fortune teller spoke to her last Halloween. There's never been anything particularly special about Brenna, but according to this prophecy, she has power locked deep down within her, and if she has some sort of hidden power, she wants access to it. In order to activate it, she has to kiss a vampire, though.
Jasper has been roaming the earth for centuries, hoping that fate would be kind enough to grant him a mate. According to the legends, he'll know his mate the moment they kiss. His mate is supposed to be a vampire, though, so why does he find himself so drawn to this tiny little human?
