For a lot of them, there’s no particular order. But there is two series:
Dangerous Lady and then the sequel is Maura’s Game.
Then there’s The Ladykiller. The sequel to that is Broken, and then there’s a third book Hard Girls.
So far, I’ve read The Take, The Runaway, Close, Faces, The Know, and Hard Girls (didn’t know it was part of a series.)
So, now I’m reading The Ladykiller and then moving on to Broken.
