Honey Cantrell was a comic book geek who enjoyed hanging out with her arcade-hopping friends. Then the aliens known as Celestials showed themselves to Humans, and Honey was thrust into a life she had never imagined. Things got worse for Honey when one of seven Celestial Orbs chose her for a role she was not qualified for. The Celestials needed a captain for their massive ship, a ship with a mind of its own, and the Orb selected Honey. Honey had barely adjusted to the new responsibility when her Orb revealed a new, darker secret. Her humanity was at risk. She had become the reluctant subject of an illegal experiment implemented by her Orb's previous owner. Her body was changing and no one knew what to expect, least of all Honey. With her future up in the air, she is forbidden to share her secrets with anyone. Resenting the lack of control over her own life and her new responsibilities, she closes herself off. Honey attempts to be as unsociable as she can...until she meets her new partner, Sammus. After that, she is forced to deal with unexpected feelings, jealous squad members, a plot for revenge, and a dangerous alien mating ritual. All Honey wanted was to be invisible but it's getting harder and harder. Can she build a relationship with Sammus? Trust her classmates? Lead a ship filled with aliens? Most importantly, can she learn how to thrive in this new body, now that she's only Mostly Human?
