Better Angels - Steven D. Brewer - Bog

The Better Angels. Entertainment. Music and Dancing. And Rescues!
Originally designed by the Magicorps corporation to be singing and dancing idols, the Better Angels are non-human biological androids that look like young girls. But their design was repurposed for nefarious purposes.
After a mysterious guardian angel named David rescues them, they need to somehow find their own way in a big galaxy. And what better way than by returning to their roots as magical-girl idols!
Quickly gaining galaxy-wide fame, traveling in their starship Angels' Wings, from their permanent berth on the Truck Stop at the Center of the Galaxy, David and the Better Angels jump from planet to space station to asteroid, singing and dancing, offering benefits for charity, and offering appearances for their fans.
But is that all they're doing? Some wonder ...
Seemingly magnets for trouble, the Angels attract more than their fair share of unwanted attention. But they also collect new allies along the way.
