The Elf Queen is truly a masterpiece. The journey of Wren and Garth is amazing, and I won't give anything away about the "Elfstones," but the Elven magic, not just the stones, in the book is very, very cool. I have always liked Brook's epic scale of the battles really amzed me in the other books, but his use of magic (And the splinterscat) is awesome. Read this book!
