 It was fairly good, a bit long winded and jumps about a bit much without explanation. 
 I enjoyed some of the characters though and think that is where Mr Selby's talent seems to lie - Characterisation. 
 There is a lot better out there in the same genre... Also I think there was a serious flaw which would be great if someone could clear up (in the spoiler below) 
 If you're thinking about this, do yourself a favor and read the First Law by Joe Abercrombie instead. Starting with The Blade Itself

 If Kailen was the Red, how did he not know who was killing the 20? They were used as an intelligence source against the 20, if he had known then surely he would not allow them to go around killing them?
