The Safe-Keeper’s Secret by Sharon Shinn.
Sharon Shinn is the author of the Archangel series for adults. I enjoyed the first several books in the series, but after that it got stale. I think that this book for young adults really returns to the freshness of her first Archangel books. The society she has created is unique and vivid. Her characters, including the adults, are complex and real. This is a real gem of a book where the reader may guess the secret from the beginning, but becomes the safe-keeper of the secret as well. It is a moving and magical book.
This would be a good booktalk book with its themes of secret keeping and dream making. Encourage girls who enjoy light fantasy in their books to try it. Also kids who like medieval stories will enjoy this one, because the touch of fantasy and magic is not overwhelming.
