I finished #7 a bit over a year ago. So there would have been memory issues about the characters and continuity, but this one kicks off a whole new series, and I did struggle with 'back' references.
Also, my memory and expectations of the prior series were of a whodunit, if I remember correctly, and this wasn't. This was high action thriller
The was the impetuous Jamie, continuously putting herself and others at risk, going way off the beaten path of normal 'police' procedures, in a new location, with an old buddy.
The first chapter is a butt grabber, but then credibility goes off the beaten path as to her involvement in the law enforcement world in England. Didn't know things could work that way.
If this is the new shift of story line and 'genre' I probably won't continue with the series after reading #9, assuming I can continue to stand Jamie's antics.
