Reading this book is like stepping through a tapestry into a poem. t shines like a sunset over water like a dragon's hoard in the firelight. The story is clearly inspired by Arthurian legends and Romantic poetry, and McKillip adds in her own patented lyrical wordsmithing, creating a real modern folk tale. It's well worth a read.
