She awoke later to find herself in the secret village of Aiedail, located under the streets of Boston, Massachusetts. The village leader, Lucius, has been told of a great prophecy that states that the source of all evil, a vampire named Jack Weston, will finally be taken out by Sam. She goes through rigorous training and with the accompaniment of Devin, another vampire from Aiedail, and a rogue leader named Benjamin, they go on a quest through the wilderness of Russia to seek out and kill Weston. Her mission could decide the fate of both the mortal and vampire worlds. She cannot fail.
