Onyx Sullivan is a shameless nerd who enjoys cheesy B-tier sci-fi shows, video games with absurd lore, and ranting about her controversial opinions relating to time travel as a plot device.Much like her favorite Starfleet captain, Onyx is an unabashed woman in STEM who loves black coffee and explorations of the unknown.


One human. One Icthian. Three days alone on a spaceship.

His obsession with her is forbidden, but close quarters puts that to the test.
This is a cozy slice-of-life novella set in the Tau Ceti Awakened universe, but it is not light on spice. Indulge responsibly.Available in the following locations:Amazon
