Bloodline

Long ago, the vampires wiped out all of the werewolves. With no one to protect them the humans soon became slaves to the demons. For centuries they waited for the anyone that could save them.
Eryn and Michael lived an ordinary life of studying, stressing, and antagonizing the vampires. That all changed when a vampire was reported dead---and they were the only two suspects. Running for their lives they make new friends and new enemies, all the while learning about the secret that ran through their blood and what they were destined to do.
