I was fortunate to be able to read an advance copy of this book. A Cavern Of Black Ice is a masterpiece of storytelling, which begins the author's latest trilogy, Sword of Shadows. That this is only the beginning of the story is remarkable, considering the epic scope of this first volume. From the first page, the book transports the reader to a world of great beauty, and even greater danger. While set in the same world as The Book Of Words, the portion of the Known Lands we find in this book is a harsh, demanding environment of ice and snow. This is a land where society exists, not so much as a way to maintain order, but as an essential ingredient to one's survival. If you are the type of reader who immerses himself or herself in a book, then be sure to wear warm clothing and turn up the heat while reading this one, or you will be feeling the frostbite on your fingers and toes. The book also contains the author's usual assortment of complex, multidimensional characters. In keeping with the setting, this is a dark story, full of unexpected plot twists. A real page turner. I can't wait to read the rest of the story in the subsequent books of the series.
