Latest release

A Covenant and a House Divided

Released June 10, 2026

Jessica Keller has faced down fleets, broken sieges, and fought her way across the Inner Stars. But Aldebaran is a different kind of battlefield. The LoS capital is a hundred-kilometer station orbiting a dying red giant, home to a thousand-member assembly of AIs and organics—and it's fracturing from the inside. AIs who were once moderates are turning hostile overnight. Allies are becoming strangers. The NOS is growing bolder, and the isolationist faction smells blood in the water. The LoS president is losing his grip, and if the alliance collapses, every organic in LoS space could be next. Sabrina's crew has seen this before—ideology sharpened into something it was never meant to be. But what's happening on Lunic Station goes deeper than politics. Something is buried in the station's infrastructure, something old and patient, and it's been rewriting minds for years. To stop it, Jessica will need to trust her AI crew to go where she can't—and make the hardest decision of her career. Because saving the LoS might mean leaving part of her family behind.
