Merrie Haskell's The Princess Curse
I'm a sucker for books reworking the story of the twelve dancing princesses--this one is set in a small Eastern European kingdom in medieval times, and centers on a young herbalist's apprentice, who's determined to break the curse to win the prize that will allow her to buy herself a place in a convent to continue her education. All sorts of excitement ensues, and I like that things went in a slightly unexpected direction. This book begs for a sequel, but I'm not sure if one will ever come out. Alas. A-.
