Without her guardian angel to protect her, she is left to rely on vampires who have their own reasons for everything. The attraction between her and Lucious grows, whether it is a side effect of the soul-bond they share or of their own volition. Yet, how can they be certain? With the help of her new friends, they must seek out a Demon Gate and enter the Demon Realm to stop Lazarus from claiming her and Lucious' souls. But, will they succeed or perish as the only weapon that can kill a demon has been lost centuries ago.
