Living with an enemy

The Alpha of the Ferrari pack, Deangelo Ferrari is known to be the most brutal alpha in the werewolf world. He has no mercy for anyone he terms his enemy and he has only one enemy which is the Amato pack. He had sworn that every single one that belonged to the pack will be killed, old and young. But then he found a lady in his bathroom, bruised and dirty, and she somehow stole his heart before he got to know that she was an Amato. 

Forgiveness is not an option to any Amato, he says, but what happens when he finds out that he's been living with the enemy all along?
