Keladry of Mindelan is the first girl to try to become a knight openly for over a century.
The training master (lord Wyldon) is firmly against this. Girls are squeemish, they can't fight, they don't have the right figure, right? WRONG! What do you expect if the most dangerous thing you make them do is embroidery?
Lord Wyldon doesn't want her to be given a chance at all, but, after all, it is now possible for girls to try for knighthood. Still, he gets to put her on probation, she has one year to prove she can keep up with the boys and if she can't, it's into the convent for her.
Kel isn't welcomed by most and detested by some, yet with her (what I think) friendly manner, she makes herself some good friends. She learns to ride, fight, solve mathematical problems etc. When Lord Wyldon finds out she's afraid of hights he makes her climb every height possible.
This is a year of fun, excitement, humiliation and desperation for Kel. Will she prove herself worthy?
