I recently read Song of the Sparrow, by Lisa Anne Sandel. Although poetry is certainly not my favorite form of literature, I enjoyed this particular book. It is a version of the story about Camelot, from the perspective of Elaine (the subject of the poem The Lady of Shalott). Sandel writes about themes like freindship, understanding, jealousy, and self-confidence in a poetic format. Through learning about Gwynivere, a seemingly vain girl, Elaine comes to realize more about herself and the people she loves. I would recommend this book to anyone who enjoys poetry or the story of Camelot.
(Megan, the latest book in the series you were talking about came out a few days ago, I believe it is titled Burned)
