I'm a librarian who loves anime, manga, and reading a wide variety of genres.
I've been mentally matching up the characters in this book to the Firefly characters I feel like Chambers might have had in mind. Here's my list so far:
Ashby = Mal (not really, but the closest fit I can find)
Sissix = Zoe, with the potential for a bit of Inara
Rosemary = Simon
Kizzy = Kaylee
Jenks = Wash
Lovey = ?
Dr. Chef = Shepherd Book
Corbin = Jayne
Ohan = maybe River, a little?
