Summary: It appears out of nowhere—one moment the sky is empty, the next, there’s a rent in the fabric of space itself. And nothing in the system will ever be the same. In the far reaches of the Rim Mountains, itinerant field-scientist Aran Romeu is searching desperately for the cure to an incurable disease—one that’s slowly killing his best friend. He’s sworn to do whatever it takes to find it. But when the portal opens, and something comes through, he realizes that ‘whatever it takes’ will involve travelling into the uncharted space beyond the portal. And he’s not the only one after the cure, and willing to do whatever it takes to get to it first … In the weighty halls of government, Chief Justice Alba Espina is preparing a political gamble that could change the shape of the system itself. The appearance of the portal shatters her carefully-laid plans and hands her political rival a weapon he could use destroy her—unless she can delay him with the promise of a diplomatic mission through the portal. But the stakes of the mission are higher than just her personal ambition. If her diplomatic mission doesn’t succeed, it might just spell the end of humanity itself. In a remote spaceport, Savina Moya, the system's most talented assassin-for-hire, is on the run again after her latest murder. But when a deadly government agent is sent after her, with instructions to bring her back dead or alive, the diplomatic mission heading into the portal may hold the key to Savina’s survival—if she’s brave enough, or desperate enough, to take it. No one knows what’s beyond the portal. And as the three of them are drawn inexorably together in uncharted space, with no idea who is an ally and who is an enemy—it’s an open question if any of them will live long enough to find out.

Summary: Enslaved by demonic aliens, a teenage boy must first survive if he is to avenge his murdered father. A typical Alaskan teenager, Paul’s greatest joy is hunting and fishing with his father. But when alien demons attack his family’s isolated cabin, they shatter Paul’s comfortable life. After killing his father and enslaving Paul, his twin sister, and their mother, the demons teleport their three captives to Hell, a desert world in the Demonic Empire. Once there, they face one of two terrible fates. They can either live as useful slaves or be immediately slaughtered as food for the merciless demons. With his demon masters demanding their slaves’ absolute obedience to their brutal human overseers, Paul soon learns to hide his burning hatred and desire for revenge behind the stoic expression of a servile slave. But as the years slowly pass, Paul adapts to survive, first as a field slave and then as a gladiator.
