Summary: Once upon a time, it was a tough world for a young princess. What happens to the world when the princess decides to get even? Aeryn Stonebreaker is the Princess of Shadows, second in line to the throne of the Light, Shadows, and Dark. The singsong her nursemaids give her is, “Gimlé is wide and bleak, Aeryn is small and weak.” It’s a hard life on Gimlé, a strange world with a red sun that does not move in the sky. Generations before, Aeryn’s warrior-king ancestor, Arthur the Hammer, unified the land and established a detailed Code of governance and behavior. But while Aeryn is a child, obedience to Arthur’s Code is fraying and the kingdom is ripped apart by rebellion and war. She grows up amid the ebb and flow of fighting and the losses it causes. What is the fate of a young girl in a patriarchal world where a princess is nothing more than a token on the game boards of powerful men? However, this is a princess who stops playing by the rules and picks up her own weapons. What happens then?

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.
