I think Steph performs a wonderful character profile with Jant, and the series basis is damn interestic (the Circle).  I also thoguth the conceptual possibilities of Shift is a nice touch, and thought the flashbacks to Jant's past, depicting a dickensenain feel were the best parts of the novel.
That said, Steph dialog sometimes leaves something nto be desired and it a bit of a 
deus ex machina  ending to the plot.  I really enjoyed the concept and the peripheral stories much more then the linear main story.  At any rate the weaknesses can be attributed to being a new author.
I had the opportunity to interview Steph 
hee if interested, and for my full thoughts on 
The Year of Our War, I reviewed it 
here
At any rate the possibilities IMHO overshadow the flaws, but ehy do certainly exist IMHO.
