The War for Survival (Survivors #2)

It's been seven years after Erika finally came home to her family. As nice as it may be, the world is still plagued with vampires. She's spent the last years training for a war she knows is coming.
Erika leaves the sanctuary in New York to find a group that's been heard about but never has been found. The large group is preparing for a war against the vampires. And Erika wants in.
But the leader of this group isn't too fond of having the princess join and fight the rabid creatures. Luckily for her, its up to the director to decide.
Aleczander Nikolaev is the leader of this secret group and as hard as he tries to turn away Erika, he can't seem to get the girl out of his hair. He can't seem to fight the strong feelings that she brings out of him.
As the call for war comes nearer and nearer, the two must learn to work together to win the battle. While faceing the biggest internal battle of all, their feelings for one another.
Will the two make it? Or will the war bring them both to a bitter end?
