The Ghost Fleet

Grant Stone and his crew just want to be left alone. They fly at the edges of Alliance space, surveying new systems far from the problems that brought them all together. Some are former military, while others have more colorful pasts. Everyone aboard the Fallen Angel has a reason for staying on the fringes. It's a good life, but a chance discovery will change everything. Confronted by an enemy powerful enough to threaten all of human civilization, Grant and his crew are forced to choose between confinement or joining the Ghost Fleet, a hidden network of ships recruited and run by the Alliance Navy. Faced with an existential danger, Grant will lead his team into the far reaches of unknown space to keep the brewing conflict from exploding into all-out war.

The crew of the Fallen Angel lived through hell. Months after an invasion powerful enough to threaten all human life in the galaxy, they find themselves in a renamed ship with a new mission to destroy some of the enemy's more insidious weapons. When one of their own is kidnapped, Grant Stone and his crew will stop at nothing to get him back. Along the way they'll find new friends and enemies, confront conspiracies that will shake the Alliance, and fight their way across half of known space. Dex must struggle to survive on an alien world while his friends race to bring him home.

After the battle of Threnody, the Seraphim and her crew are broken. Months of relentless war by the Children, a race of genocidal artificially intelligent life forms bent on taking revenge on their creators, strains every resource available to the Planetary Alliance. The fight runs the spectrum from open combat to countless subtle plots by the Children, and it's all the Alliance can do to stave off utter catastrophe.

The crew of the Seraphim learned the hard way that saving humanity comes with getting blamed for all the collateral damage. The Alliance is bleeding but not yet dead in the aftermath of the war with the genocidal Children. With entire star systems in ruins and others cut off from accessing the Cascade for faster-than-light travel, there's no shortage of damage to go around.
