Before you pick up this fourth book, read the first three. Hearn does an excellent job of keeping the various plot threads woven nicely throughout the four books, bringing them through to the conclusion of the tale and fourth book. I like that there are multiple characters and not just one hero. This makes for a much more satisfying read overall. The writing continues to be solid and well edited. I feel the conclusion is satisfying, especially for the style this is written in. I like the sizes (lengths) of each book as it makes it easier to carry one with you to read as there is time, unlike trying to carry a huge thousand page novel around. I like the Japanese myth feel to the whole story. I like the majority of the characters and how they are manipulated. Overall, this is an enjoyable series with a well thought through story line. I received an ARC in exchange for an honest review. This in no way influenced my opinion.
