When alien ships appear over the biggest cities on Earth, he rolls his eyes and keeps scrolling. Then he is ordered to report to base, and ends up on a spaceship with millions of soldiers from around the world. The Krezikians are not here to conquer anyone: they want to stop humanity from wrecking the only planet it has. Caught sneaking out to check on a friend, he runs into Aster, who is sweet and whose tentacles have never heard of personal space, and finds himself made Earth’s unwilling spokesperson.

Portals split the sky open, and the monsters of Erethar who come through have no interest in conquering Earth: to survive, they need something very specific from humans. The government starts recruiting for a ritual that sounds a lot like a cross-dimensional booty call, and Everest Hale signs an exclusivity contract with Rathyn of the Dark Vale. It is supposed to be an arrangement, until Rathyn melts under his hands and Everest starts to suspect the government is not telling the whole story.
