The Cold Between was my introduction to these characters. I suggest reading it too but this stands alone quite nicely. The Corp personnel, Shadow Ops, PSI and the tribes find themselves manipulated by a major corporation and a reclusive group of colonists find themselves in the middle of mayhem.
Nefarious activities don't always work out as well as the miscreants plan. This leads to vendetta mentality rather than police action. The characters are developed nicely with depth and color. Bonesteel does an excellent job with her characterizations. The romantic interplay was more prevalent in the first book and still exists here but it does not seem as important. That isn't to say that a certain amount of relationship tension is apparent.
I really liked this book.
