It's been 300 years since humans arrived on Neophia and the planet's intelligent species have yet to agree on how much influence humans and their advanced technology should have on the planet. With the threat of war hanging in the air, Lieutenant Commander Crystal Wolf races to finish construction of the mega submarine, Journey, in order to calm political tensions on Neophia and cement her already stellar military career. Lieutenant Desiree Flint never dreamed she would leave Earth to serve on Neophia, but with the end of her military career in sight she doesn't see a way around it. Determined to rebuild her reputation on Neophia, no matter the cost, she sets her sights on dethroning Commander Wolf in order to prove her own superiority. When Journey is attacked by someone from Crystal's past, the two women must find a way to work together to save the ship, liberate an underwater colony from an oppressive government, and prevent a war.
