This is a good sequel, but not great. Now, this may be due to some of the plot lines going into the third book, but i was disappointed with some of the smaller plot lines.
For instance, Grunt. From what i can tell, there was NO point to that at all. The ninja woman as well (can not remember the name) - comes to the story, does some kung fu stuff, then has to leave. These come across as just padding.
Kane is great. Shame the whole book could not be about him only (and Wolf - fantastic).
Cole is becoming an interesting character, and i am eager to see where he ends up.
Sasha, not too interesting this book - maybe next.

Highlight, the Ironman. Loved the inner turmoil this character had, with the sudden outbursts of his contempt for people. Yes, he was a grade a cock, but i loved listening to what this character was up to. A little disappointing at the end of the book - wanted a little more, but there you have it.

A good series, but nothing outstanding for me. Maybe the next book will up this series to a 4* (as it is currently at a 3.5*).
