Gazhena Hadal is Gatekeeper of the Outpost, a covert organisation established during the Energy Wars - the war for the last of Earth's resources. Stationed in the deadly zone known as the Courtyard, he defends humanity's best chance at salvation - a meteor fragment with special properties known as 'electronite'.

But his fight is no longer just against the criminal conglomerate running the world. Off world entities - and the demons that have lurked in the shadows for millennia - seek to snuff out electronite's light.

Keeping the underworld at bay is his day job, but after a Reptilian general opens a portal in the Courtyard and leads demons into their reality, Gazhena knows they need allies. He's seen the forces of darkness at work, and he's also heard the rumours about the Blood Moon. If the enemy returns during that window, before the Outpost has found reinforcements...

But revealing the existence of electronite to an Earthbound force would also mean their end.

Then Akityl, an extraterrestrial claiming to have sent the meteor fragment, arrives. His people have fallen to the Reptilian onslaught, but he believes he can still save them with the Gatekeeper's help.

Knowing Akityl is their best chance at survival, Gazhena must form an unlikely alliance and step into another's world. They'll have to overcome impossible odds and their own private hells - all before the Blood Moon rises.

The politics are beyond perilous. When even demons have masters, it's clear the fate of all their worlds is intertwined.
