Summary

Mars’ (D-SEA) Deep Space Exploration ship Tranquility has been dispatched to an anomaly detected in a far-off star system. Awakened early by the ship's artificial intelligence, Captain Dan Welko and his crew face danger at every step of their mission, including first contact.

Meanwhile, back home, war brews between the One World Religion of Earth's (TFA) Terran Forces Army and Mars’ free people. It is up to Admiral Meredith Welko, her team of warriors Aces and Zephyr, along with her smaller fleet of warships of the (MDF) Mars Defense Forces to protect her people.

Conspiracy, war, deep space exploration, and the essence of creation are explored.
