NERVE by Leah Ruth Hart
Tezzix has been isolated her whole life, groomed to join the Council that rules her planet.
Before she joins, she must visit Earth and the floating city of Nirvana.
She's been taught that humans are vile creatures.
Yet, among humans, Tezzix finds deep friendship, forbidden attraction, and the first taste of freedom that she's ever known.
After all that, how can she ever be convinced to return to her duty?
