Brutal Alien (A Sci Fi Alien Abduction Romance) (Vithohn Warriors) by Stella Sky

This book is the second in the Vithohn Warrior Series. Earth is a dystopian society with packets of humans living hidden from the Vithohn aliens who devastated Earth. Apparently what saves the earth is that our female DNA combines with the Vithohn and takes their aggression away and makes them reasonable. This book is about the Vithohn and humans making an alliance because the Vithohn enemies the Kalari are coming. I like the concept, but from what I see is that earth will become little halflings of Vithohn males and human females.
