Didn't like this very much. It was a fun story but not given the detail I would have appreciated. Then again, it covers a few years in a girl's life in not too many pages, so I guess it had to skim a bit. Also, might be the children/young adult aspect that doesn't allow to go as in-depth as I would have liked. 
 Might read the further adventures, but my library's missing #2 and I don't feel motivated enough to ILL it. 
 Story of a girl who wants to be a knight, not a nun or a wife, so she switches place with her twin brother so he can go learn to be a wizard and she can train to be a knight. Things are tough, but she finds friends and inner-strength to get her through her trials. The story so far ends with her going t become squire to her friend, the Prince.
