Summers at Castle Auburn by Sharon Shinn

Lowborn Corie, the impressionable young heroine, spends her summers with her highborn sister, Elisandra, at Castle Auburn and the rest of the year in a village apprenticed to a "wise woman" witch/herbalist called Grandmother. Corie accompanies her Uncle Jaxon on a hunt for the Aliora, faerielike creatures who serve as unwilling slaves to the humans inhabiting this quasi-medieval world. Also along for the ride is Elisandra's future husband, Prince Bryan of Auburn, a vain 16-year-old adored by most girls (including Corie) and loathed by most men. As Corie ages, she gets over her crush on the increasingly narcissistic and self-indulgent young prince. The relationship between the sisters deepens along with the plot lines revolving around Jaxon's obsession with the Aliora and their queen, Rowena. (Publishers Weekly)

Although the story was somewhat predictable, I thought it was a nice "fairytale" and would easily give it five stars. If you enjoyed The Goose Girl or Seer and the Sword then you will like this book.
