Went 53 pages last night...hated to put it down. It's good. Lots of sexual stuff, but in Heywood's hands, it's a bit more corny than titillating.. Lots of Indian stuff.
There's also Steve Hamilton, who for some reason, keeps getting awards, but I don't think he's as good as he used to be. His character, Alex McKnight, is too egotistical or something.
William Kent Krueger writes about Minnesota, and he's always been good, but I tired of him in just the last book he wrote. His Iron Lake, the first one is great, really good. Cork O'Connor, his protagonist, has turned into a goody two-shoes. But the series might get better since his wife was killed, didn't like her anyway.
This Buzzelli woman - I have 3 of her books on hand, am waiting for the first to get here to I could start - she writes about the UP...
Then there's Henry Kisor....

And try Thomas Perry - he's not Michigan, but he's good...especially Metzger's Dog...
