A signal identical to the one from Verath-9 arrives from a place where no civilization should exist — and this time, someone aboard the Limiar itself is sabotaging the mission from within. As Commander Halen tries to trace the signal's origin, she discovers the ship's systems have been remotely altered, the logs tampered with, and one of her own crew has been following orders he never revealed to her.

Why readers love this book

  • The betrayal comes from within — and it changes everything you thought you knew about the Limiar's crew
  • The truth about the Non-Interference Directive starts to surface, and it's worse than anyone imagined
  • An institutional antagonist who never has to appear on screen to be terrifying
  • Mission three of the Commander Halen saga, at the point where everything starts to unravel

For readers who want science fiction with real political and ethical weight, not just action. The truth is closer than the agency would like. Read it today.

VOL. 4 Cover of Return to Eridani

Return to Eridani: A Space Opera Novel (Commander Halen #4)

After violating the very law she swore to protect, Commander Halen returns to AICR headquarters to answer for everything she's done — and everything she's uncovered. The man who architected decades of institutional silence is waiting for her, and this time he won't operate from the shadows. Halen walks into the final hearing carrying, literally under her own skin, living proof of everything the institution tried to erase.

VOL. 2 Cover of The Crystal Portal

The Crystal Portal: A Space Opera Novel (Commander Halen #2)

The echo left behind on Verath-9 wasn't a distress call. It was an address. When the Limiar reaches the coordinates the signal pointed to, it finds a crystalline portal suspended in the void — a structure no AICR catalog recognizes, leading to a world that, according to the official record, shouldn't exist. Commander Halen must decide what to do with what she finds on the other side before the agency decides for her.

VOL. 1 Cover of The Trail of the Black Pulsar

The Trail of the Black Pulsar (Andromeda Saga #1)

A pulse of radiation arrives in a pattern that shouldn't exist in nature — coming from a region with no star ever catalogued. Commander Kael Drenov diverts the Andrômeda from her assigned route, against direct Fleet orders, to investigate. What the crew finds is a beacon built by a long-extinct civilization — and what it's guarding could rewrite the balance of power among the stars.
