Found it an enjoyable read, especially since it was the first book to portray the new directions of Necrons as Tomb Kings in space. Having always loved egyptian lore, Im quite taken with their new direction as a more neutral force.
Yes, Cato Sicarius needs to die. And it should be pointed out Fall of Damnos is only one half of the story. There supposedly will be a second book.
I find Battle for the Fang to be the best of the Space Marine Battles, followed by Fall of Damnos.
Didnt particularilly like Hellsreach or Legion of the Damned, felt both had fairly forgettable plots, and the LoD wasnt used very well I thought.
