I am actually reading this one right now. I'm all caught up in other words!
From the Blurb:
Ten years after surviving special operations in Afghanistan, Danny Clay is working as a scriptwriter in the emotional war zone of TV production. His best mate and editor is Vietnamese neighbour Zan who may or may not have killed a man with her bare hands. When their writer friends start dying in mysterious circumstances, Danny must resurrect his old army sapper skills to prevent himself and Zan becoming the next victims.
