Force of Blood (A Woods Cop Mystery)

"Late spring 2007.  Michigan in economic freefall, politics reduced to nastiness, state jobs being erased, and personnel furloughed without pay.  Grady Service, detective for the Department of Natural Resources in the Upper Peninsula, watches as his colleagues leave the department one by one.  Upon being asked by an old friend to look into unspecified problems his son is facing on the shores of Lake Superior, Service has no idea how complicated his life is about to become.  All he knows is that the situation involves something his friend calls "bleeding sand" and that his new partner, Conservation Officer Donna "Jingo" Sedge, is the oddest young officer he's ever met."
