Book two in Sten series and I am craving more. The first book set up our main character and trained him. Wolf Worlds lets him do his thing. The authors create a really interesting challenge for Sten as he gets to defuse a conflict between some sects of a religious group. These folks just happen to live right in the way of a new mineral that the Empire needs.So, Sten gets to go without use the tools that his Mantis Section training has given him. Instead he has to be a bit creative to keep the mission moving in the right way, but without all of the support he might have grown used to.I like the story, but I really like Sten. He remains a somewhat conflicted hero who isn't comfortable with every decision he has to make nor is he guaranteed to succeed at everything he tries. Things work out, but there are bumps in the road that threaten the mission. It's good stuff and worth buying from someone used.
