Force of Blood — Joseph Heywood

Late spring, 2007. Michigan in economic freefall, state budgets being slashed, politics reduced to nastiness, state jobs being erased, and personnel furloughed without pay. Grady Service, detective for the Department of Natural Resources (DNR) in the Upper Peninsula, watches as his colleagues leave the department one by one, leaving him without his old support system. 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, both jealous and suspicious of his role in what she views as her case on her turf.

Service and Sedge become immersed in a centuries-old mystery they must solve in order to deal with the current and more pressing problem: people willfully looting and tearing up a Native American archaeological site. As past and present intersect, summer lightning ignites a forest fire in northern Luce County, and the blaze quickly covers 20,000 acres. The story moves at breakneck speed as Service, nearing three decades as a Woods Cop, finds that expectations seem to be changing on all fronts, personal and professional, and he is not certain he can live up to them.
