Love in Enemy Territory

Lana has a dangerous job that the people around her are not aware of.
She works as a spy and is deep inside the enemy lair when new feelings of love catch her unawares.
The work she does requires her to trust no one in the Castle and have everyone under her spell. She has one of those parts down and it is becoming harder and harder for her to keep her heart safe from one of the men in the Castle trying to woo her.
One of the people there is an undercover agent just like her.
But which one is it?
Is it the one she’s falling for?
