The rating is 3,5.

What started out as a pretty slow start ended in a roaring bang. It finishes the story of Prospero and introduces the Space Wolves in the 30K universe.

I would, however, like to give Mr Abnett a slap over his face for the constant use of "wet leopard growl", not to mention "wet leopard purr". What even is that?

All in all, it's a good read. Probably better on the reread.
