It's listed as part of the Troubleshooter series, which apparently follows the group of main characters seen in the book - which as book 8 of 12 is coming in a trifle late, I suppose - composed of Navy SEALs, ex-Navy SEALs and an FBI counter-terrorist team primarily.
I enjoyed reading it, and really liked how she handled the interplay of the different characters - who, in a romance novel first in my experience, are not all heterosexual. Kind of refreshing. It would be a good airplane book, and it was great to have around yesterday because getting drawn into reading it pulled me out of kind of a problematic and unpleasantly funky mood, for which I am grateful. Thanks again for lending it to me, faintheart.
