The Seven: The Second Invasion — Benjamin W. Schenk

It's been two years since King Benniben and his allies ended the threat from the Lizasarian race, and the population of Earth has been severely decimated. Now the Elementians and their Earth friends face the greatest threat to humanity's extinction. But will their powers be strong enough to defeat such vicious enemies?
"The Canusians look human, and primarily they are, but they have a lot of the characteristics you would find in your dogs. They eat their prey alive and are very powerful, no matter what size they are. The Felonians are just as vicious. They won't eat their prey alive but they will give us a chance to get to them before they kill them "
"How?" Rhea asks, looking at the worried Melanie and Sissy.
"They are like the cats on Earth." Sandra says. "They play with their prey before they kill them. And they are very conniving. They know that to get to King Benniben and me, they will have to use your kids and our kids as bait "
