The Little White Horse, by Elizabeth Goudge

Even though this book was written in 1942, I had never read it until I discovered it at a used book sale this summer. The language Elizabeth Goudge uses drew me in to a fantasy world described in perfect detail.
Thirteen year old Maria Merriwether travels with her governess in Victorian England to Moonacre Manor, the home of her great-uncle Ben. She is delighted with her new home and her perfect tower bedroom with a small door just her size.  But mysteries and secrets abound: Who lays out her wonderful clothes each morning? What kind of dog is Wrolf, and is he ferocious or tame? Who are the Men of the Black Wood and why do they do such evil things? Maria meets many unusual characters and animals in the book, and they all help her fulfill her destiny as the next Moon Princess.
This book will probably not appeal to all children; there is a lot of description and the writing is slightly old-fashioned, but some children and adults may certainly want to try it out. I did read on the internet that a movie has been made from the book, The Secret of Moonacre.
