Perfect for you if...

  • You love hard military sci-fi with realistic tech and genuine stakes, not just explosions for show.
  • You're already invested in the Legacy Trilogy and want to see where the time-dilated conflict leads next.
  • You enjoy space opera that treats combat tactics seriously and gives soldiers agency beyond being cannon fodder.

Maybe not for you if...

  • You prefer character-driven narratives over military strategy and tactical operations.
  • You find alien contact stories more interesting when they focus on cultural exchange than on combat.
  • You haven't read the first book and prefer standalones that don't assume prior knowledge of a sprawling universe.

About this book

A wormhole in the Sirius system stands between humanity and an alien threat in this science fiction thriller. The 1st Marine Interstellar Expeditionary Unit has successfully freed thousands of enslaved humans from alien control after distant battles. However, Earth has aged twenty-one years more than the home planet the Marines originally departed from, and they require time to retrain and readjust. Before they can recover, a detachment of Marines mysteriously disappears. The investigation points to an ancient wormhole threading through the Sirius system. The Marines must venture into the unknown to confront whatever lies beyond—whether an ancient enemy or a new threat. Their mission could have consequences that reshape the universe for millennia to come.
