'Kelty is a C-grade citizen of the Greater Melbourne Megalopolis, a city filled with towers that stretch halfway to the sky. While Skywalkers - the A and B-grade citizens - live above the clouds with access to all the wonders of the 21st century, Subbies like Kelty must dwell in the darkness of the streets below. Desperate to avoid her perceived destiny, Kelty is faced with the unthinkable: a choice between a hopeless future or leaving everyone and everything familiar behind to join the Space Corps. There's one catch - first she must give up her body for transplant'. Source: bookseller's website.
