After leaving Earth's orbit behind, the spaceship Velocity and its crew hurtle through the galaxy toward their alien ancestor's homeworld, Dwynna Major. Trouble arises when Chief Engineer Claire Gordon's neural interface device malfunctions, and she secretly struggles to retain the knowledge desperately needed to keep the Velocity running. Adding to her fear of failing, Claire's falling in love with the only crew member that's untouchable--Captain Holly Crowe. Holly's only priority is to keep the crew safe as they face the unknowns of interstellar space. Maintaining the strict rules and regulations of her captaincy is the only way she can lead, even if it distances her from the rest of the crew. When Claire's failing interface puts them all in danger, however, Holly's rigid approach to command is called into question. Will Holly and Claire continue their mission to Dwynna Major even if it puts their lives and their hearts at risk?
