Iron Lake — William Kent Krueger

Chicago cop Cork O'Connor and his lawyer-wife Jo moved back to his northern Minnesota hometown of Aurora to improve their quality of life, but it hasn't worked. Cork became the local sheriff, but lost an election after a disagreement between local Indians and whites over fishing rights turned deadly. Then his marriage broke up, with Jo becoming a successful advocate for tribal rights and Cork reduced to running a scruffy restaurant and gift shop. As the book starts, Cork is feeling guilty about sleeping with a warm-hearted waitress and still hoping to get back with Jo and their three children. Drawn into the disappearance of an Indian newsboy, which coincides with the apparent suicide of a former judge, O'Connor clashes with a newly elected senator--the judge's son and Jo's lover--as well as with the town's new sheriff and some tribal leaders getting rich on gambling concessions.
