Errant by Diana Peterfreund

Set in the Killer Unicorn universe, this novella takes place in 18th century France.  It is a tradition of the nobility to  hold a unicorn hunt before a wedding to prove the virginity of the bride.  When Sister Brigitta of the Order of the Lioness arrives with her unicorn, she is surprised to discover not only is the bride of the bloodline, she also has the power as well.  Together the two find a way to save Elise from the men trying to control her life.

I really enjoyed the story.  At first it was frustrating because neither Gitta nor Elise has any interest in trying to understand each other, but once they come to see the other's point of view was great.   I liked the whole story and I think it added something to the story that was started in Rampant and Ascendant.  It was interesting to see in this world how unicorns are accepted and something known even if they are scarce.  And how the world generally views unicorns and unicorn hunters.
