From Beyond The Stars by Dakota Hatch

Cassius doesn’t trust Novae. For one thing, he’s a living blob of slime. For another . . . well, he’s an alien.

But Novae needs his help. Something . . . someone is after him.

An extraterrestrial overlord, to be exact—set to consume Novae and destroy Cassius’s world.

Forced into a quest to send Novae back to the stars, Cassius and his friends are running for their lives. If he fails, he, his friends, and the entire world will be torn apart. People will die—and any survivors will have their brains hijacked, only to become slaves to the faceless overlord looming over the planet.

In short, if Cassius fails, everyone is doomed.

No pressure.
