Again Loken is one of the main characters as we see him struggling to be true to the Emperor as seemingly all around him plot treason at every turn. Loken is sent to the surface of Istvaan III with the other loyal Space Marines and fights the bloody war against the Istvaanians in their capital city.
Other loyal Space Marines are also trying to foil the plans of the Warmaster in their own little way against the large forces turned against them. Also the Cult of the Emperor has grown with the addition of a Saint and an Apostle.
Counter has produced a fast paced read that has to bring together a lot of the threads from the previous two novels. Overall a great read.
