Angel With The Sword by C.J. Cherryh
Paperback. Condition: Very Good. 1985. DAW.
In Merovingen, a watery canal-laced city, much like Earth's Venice, society is segregated along class lines between the lower and upper cities. Against her better judgment, Altair Jones, 17, rescues an unconscious man from a canal near her poleboat. She is fascinated by Mondragon's good looks and elegant ways and begins to fall in love with him. Even though she knows there is no future for a water rat like herself with such a man, she decides to watch over him and rescue him from his enemies; enemies who turn out to be the most powerful people in the upper city. Cherryh is well known for her skill at creating complex and believable societies and worlds, as is shown by this book's 40-page appendix of maps and essays that cover everything from Merovingen's history to its monetary system. This meticulous background work shows up in the reality of her descriptions of the city, through which readers can almost feel the rotting dampness of the canals.
