Shadow Warrior Retribution

Outlaw Gangs
Extraterrestrial Beings
Neither would take what didn't belong to them

Ferris and Carline had dealt the Invaders a major setback. Now they were forced to leave the beach area of Waikanae and move inland towards the center of town. They discover by accident that the outlaw gangs had claimed the town for their own and were collaborating with the invaders. 
After helping two women escape from their attackers, they lead them to a building they considered safe. Things however were not what they seemed, the building held its own secrets, as does one of the women they'd just rescued.
Close bonds form between the four of them that quickly developed with each of them knowing they might not survive for much longer. 
A mysterious hill known as 'Green Mountain' seemed to hold the key to something both the gangs and the invaders were after. With the aid of the women, they intended to find out what was there both groups wanted. 
They discover that the collaboration of the gangs with the invaders was just the tip of the iceberg. It ran a lot deeper than any of them could ever imagine.
