At Galactic Central

Galactic Central, a collection of floating cities in a vast, manmade, planetless cloud. Scout Shannon longed to see it since she first heard of it. This place long represented her shining future.
But in her less shiny present, she reaches it by smuggling herself aboard a cargo ship and hides in the lower sewer-like levels of the most opulent of the floating cities. Teams of girl assassins still hunt her. Worse, her friends are in danger and don't even know.
Scout has to save her friends, because saving her friends means saving her entire planet from enslavement to the Tajaki trade dynasty. Caught between two sides of that dynasty, with a mysterious third party desperate to remove her from the galaxy, Scout is in way over her head. But with her friends, she just might see a path to victory for all of them.
