Then he'd be free to confront the deranged, body-snatching Centurion in league with the Synths and save some lives. Meanwhile, the sleeks, who showed up as Earth's saviors only to make humanity their slaves, have enlisted the Legion's services in a mercenary gig.

As a sci-fi author with a hit TV show, I have a few ideas about what alien invaders are supposed to look like. In my stories, they’re technologically advanced monsters, with tentacles, and no faces. Turns out I was right about the technology. And about how angry they’d be. But the way they look is more terrifying than even I could have imagined. They look exactly like us. Because they are us.

Where is the best place to find life beyond Earth? We often look to Mars as the most promising site in our solar system, but recent scientific missions have revealed that some of the most habitable real estate may actually lie farther away. Beneath the frozen crusts of several of the small, ice-covered moons of Jupiter and Saturn lurk vast oceans that may have been in existence for as long as Earth, and together may contain more than 50 times its total volume of liquid water. Could there be organisms living in their depths?
