HIGHLY RECOMMENDED. I am really loving this 'series'. For me Storm of Steel (Book 6) took on a different and in many ways a less violent narrative (I susect the body count was lower) as the story line was a much more personal insight into the characters themself. If I have a dissapointment it was that the end of this tale arrived too soon, and left we wanting more. Maybe that's the authors plan. I am very much looking forward to Book 7 (For new readers of this series I strongly suggest that you start at Book 1- The Serpent Sword)
