Another book on marine spaces! Certainly it is the most present, they are big and strong and very dangerous, yet the book transcribes this aspect. When you're a fan of little W40K, we appreciate seeing Tyrannidae be "kick ass (if they had of course!), It's nag, it is bloody well described! Although happy end is inevitable from the beginning, I was very surprised with some twists. Book well "fun" to read.
