Equal parts troubleshooters and troublemakers, Keene and Lexa-Blue, along with the sentient ship, Maverick Heart, have been known to solve a problem or two. For the right price, that is. Even so, they aren’t prepared for a summons from a love Keene thought long past. Daevin Adisi is now the Technarch of Brighter Light, one of the greatest corporate colony states in the Galactum, which is on the brink of war with Sotari, descendants of a people changed by nanogenetic experimentation. Seeking only to live a quiet, simple life free of the technology they blame for the worst part of their history, Sotari has struggled to co-exist with Brighter Light, which to them represents the worst of their own history. And now, the uneasy truce has finally crumbled. In his last-ditch attempt to save their world, Daevin has called upon Keene to help him finally bring peace.

The Maverick Heart is bored. That is until it discovers a top team of engineers and scientists in a barren, backwater system have created the Gate, a stable, artificial wormhole that will revolutionize interplanetary travel forever. Breaching the wall of secrecy around this radical new technology is a temptation too sweet for human partners Keene and Lexa-Blue to resist. Elsewhere, Ember Avanti is a thief, with the highest of high tech toys in his arsenal. And he's damned good at it, too. But sooner or later, every thief chooses the wrong mark. When he targets Quintaine DiaStellar, he soon learns the corporation will stop at nothing to make the Gate its own. Ember's team and the Maverick Heart crew must unite in a desperate attempt to stop the most vicious act of industrial espionage in the history of the Pan Galactum.

In a desolate system on the outer edge of Pan Galactum, the skin of the universe has ruptured, tearing open a portal to an alternate reality. Witnessed only by the sentient science vessel N'Dea, a massive, battered ship falls through, housing a community of refugees fleeing an enemy that has pursued them across the cold reaches of space for decades. But have they come alone? Summoned by N'Dea while en route from a reunion with dear friends on the Galactum's capital, the mystery is a lure that fellow Artificial Sentience, the Maverick Heart, cannot resist. It's now up to Vrick, along with humans Keene, Lexa-Blue and Ember, and allies old and new, to come to the aid of this ship of lost souls. Together they must find a way to seal the breach for good, before a ravening hunger can spill through and rip the Galactum apart. “Stephen Graham King's Maverick Heart Cycle is the queer Firefly-meets-Killjoys series I always wanted, with the added bonus of his seemingly effortless world-building, clever plots, and themes of chosen family and "no one left behind" that bring me back every time. Trust me: go get squishy.” Nathan Burgoine, author of Light and Exit Plans for Teenage Freaks “Stephen Graham King is a master builder of worlds, from the organic to the technical, and he fills them with wonderfully complex characters who just have that cool factor. The entire series is a must-read.” Cait Gordon, author of Life in the ‘Cosm and The Stealth Lovers.

As the Gate Project expands, building stable, artificial wormholes in orbit around ever more worlds in the Pan Galactum, its hunger for construction materials grows exponentially. But the discovery of the dead binary planets, Sound and Fury, may finally sate the project's hunger ten times over. In the shadow of massive, shattered Fury comes an interstellar travelling theatre, bringing with it an old friend of the Maverick Heart crew. One with a nose for trouble who soon discovers a conspiracy of embezzlement, greed, and corporate apathy too deep to investigate alone. When Ember receives the call for help, it is a mystery too enticing for him, Keene, Lexa-Blue, and Vrick to pass up. One that will take all their skills to unravel before time runs out and the whole system burns.
