(Large Print Edition) Structural Integrity is a standalone sci-fi horror thriller, and Book 1 in the interconnected Moros Universe. Spaceship engineer Helen Mitchell can fix the aging freighter Persephone, but she can't fix her crumbling marriage. When a mysterious contagion of violent paranoia grips the isolated crew, Helen's reality begins to fracture. Trapped in a massive communications blackout with failing life support, Helen must uncover the terrifying secret locked in the ship's cargo hold before the crew tears each other apart-or the freighter implodes.
