Dark Storm

Buried alive for hundreds of years in a volcano in South America, Dax worries that he has become the abomination that every Carpathian male fears, a victim of the insidious evil that has crept relentlessly into his mind and body over the centuries. But Dax isn't the only one emerging from the darkness...

His name is Mitro, and he once stood by the side of the prince of the Carpathian people. Now he is the epitome of malevolence, and perpetrator of one of the most shocking killing sprees known to man. No one escaped the bloodshed, including his lifemate, Arabejila.

Now, between Dax and Mitro, a violent game has begun - one that has marked Riley Parker, the last descendent of Arabejila, as the reward.
