I don't know why William king stopped writing the Space Wolf series, but I wish he hadn't. Not that this isn't good, but the voice is different and it seems to lack the feel of the first 3. This was still an enjoyable book, and it has all the action and excitement of the others. The Wolf blade is sent along with their charge to a planet Hyades in order to investigate interruptions in the Promethium production. It is discovered that the sabotage is an inside job and an elaborate set up to get the Space Wolfs and Dark Angels to fight, bring about the coming of a chaos god and destroy the space wolfs. ( )
