Lord Dunsany is, sadly, a forgotten authour with, besides a fantastic writing name, a skill of creating tales of such magic and fancy that it almost seems unfair what he's able to accomplish in four or five pages what modern authours can't accomplish in 500. Dunsany was a major influence on such more well-known writers as J.R.R. Tolkien and H.P. Lovecraft, though it is difficult to tell so from this collection of short stories. The Book of Wonder doesn't contain Dunsany's works on myth and legend, and instead focuses on magical, almost whimsical, stories that can range from humourous to frightening. If you're looking for the works that directly inspired those two writers I mentioned above, you may be more interested in getting hold of "Time and the Gods," or "The Gods of Pegana."
Described by Lovecraftian scholar S.T. Joshi as one of the most consistent writers of weird fiction, every short tale in this book will be sure to have you return to it, if only to pour over some of the incredibly well written prose that Dunsany filled every page with. Some of the stand-out tales are "The Probable Adventure of Three Literary Men," "Pombo the Idolator," "The Quest of the Queens Tears," and "The Hoard of the Gibbelins." Although these are the ones that stand out in my mind now, none of the stories in this book are bad; in fact, all are incredibly good and stand the test of time like few can.
If you are interested in the primordial roots of modern fantasy, looking for some unique bed-time stories to tell your children, or just want to keep alive the memory of a sadly forgotten authour, I wholeheartedly recommend Lord Dunsany's "Book of Wonder."
