Structural Integrity. Moros Universe, #1

Structural Integrity is a standalone sci-fi horror thriller, and Book 1 in the interconnected Moros Universe. In the deepest stretches of the void, paranoia is just as lethal as the cold. Spaceship engineer Helen Mitchell knows every pitted pipe and corroded valve on the USCSS Persephone, but she doesn't know her own husband anymore. As the heavy bio-hauler begins a grueling three-month transit through a communications blackout known as the Dead Zone, Captain John Mitchell grows distant, secretive, and uncomfortably close to the ship's navigator.
But a failing marriage is soon the least of Helen's problems. A mysterious, violent madness begins to spread among the isolated crew, turning friends into deadly threats. Protected only by her own stubborn logic and a sarcastic, salvaged AI drone named Seven, Helen watches her reality unravel. Is she suffering from deep-space delirium, is her husband plotting to eliminate her, or is something else entirely hunting them in the dark?When the ship's power grid suffers catastrophic, unexplained drains, Helen realizes the threat isn't just in their heads.
Something is bleeding the Persephone dry. With the hull buckling under the gravitational shear of deep space and the crew turning on one another, Helen must navigate the freezing, labyrinthine corridors to uncover the terrifying secret locked in the cargo hold. If she fails, the Persephone will become just another floating tomb in the dark.
